(Original post from October 26th follows:)
As promised, here's notes from the reader with an affected 2010 MacBook Pro 15in running 10.6.8 and therefore can't use the MacBook Pro Video Update 1.0 software update for 10.7.2 released Monday. (I mentioned in Monday's post on the update that it is not 10.6 compatible, verified by his Pacifist install attempt in 10.6.8.)

"More on the 2010 15in MBP video update (10.6.x user)
So... Went to the Apple Store here in Boston (just visiting) and took my MBP in to try to get the 'fix'. Turns out, unless you're running 10.7.2, the 'fix' is hardware based, i.e. Logic Board. I still might try to hack the software patch into submission, but will probably end up just getting the board replaced. It will be on Apple's dime, after all.
-Peter M."

(He noted Monday that his 10.6.8 system would only boot into safe mode after installing the update manually via Pacifist. Personally I wouldn't bother with that if Apple will swap out the motherboard - that way you get a later chipset, maybe even later stepping CPU, GPU, etc.)
My first thought when seeing the doc earlier this month was it's related to a specific revision of the chipset (or GPU), since apple lists specific production dates affected (mfg between April 2010 and February 2011). I guess the attempted software fix wasn't possible/practical for 10.6.x? (Or they figured it was cheaper to address it w/swaps vs dev/test time for software patch attempts, thinking most would eventually be on Lion anyway.)
  And even for 10.7.2 users that can apply the software update, they note:

... "If the symptoms persist after installing the update, select one of the (Apple store/ASP) service options..."

And the updated doc also mentions:

"Apple will service affected 15-inch MacBook Pro computers free of charge until two years from date of purchase. Apple will provide further extensions to this program as needed."

Update: As of 7/31/2012, the apple doc has been updated to note if the video software updates do not fix the problem that they will service affected models for 3 years from purchase date, which may be extended as needed. The emphasis/underline is mine, as wording is similar to the apple doc on 8600M issues that had several extensions over the years.)

"...Apple will service affected 15-inch MacBook Pro computers free of charge until three years from date of purchase. Apple will provide further extensions to this program as needed. This worldwide Apple program does not extend the standard warranty coverage of the affected MacBook Pro."

The original doc on the MacBook Pro/Nvidia 8600M repairs also had 2 years, but was revised to 3 then 4 years over time as that expired. (And with a note on further extensions as necessary.)
 

"I went from a 2x2 core 2.0ghz in a Mac Pro 2006 (Xeon 5130s).
I went to 2x4 core 1.86 ghz, 5320's without the BSEL mod. I wanted stability, and this upgrade is CHEAP. I may do the BSEL later or just wait for the 3ghz to get cheap one day. :) SSD is probably next best bang for the buck, and I've got a Radeon 4870 already. Flashed PC Card, 512M memory.
Tool note: I got a 9" 3mm T Handle for the CPU Allen screws for under $4. Grainger had them in stock in Houston. (ditto at ACE, others per older reports)

I used Arctic Alumina for the new heatsink, cleaned the old off with plastic scraper and fingernail polish with acetone as the main ingredient.

A 50% improvement on Geekbench for $56 minus whatever I can get for the old CPUs. (PDFs of GeekBench scores before and after upgrades.)

A brief scare when it wouldn't boot but I reversed the RAM risers. Another brief scare when the Activity Monitor only showed one CPU scale, but that's what it does with over 4 cores; an aggregrate.

About this Mac doesn't report it correctly of course, but benchmark-wise and using other tools it all looks and acts like it should. At the prices for 5320s, no reason not to do this mod unless you just aren't handy with the steel.

SystemLoad at 100% on all 8 cores, 82F ambient air. World of Warcraft in a window with fairly high settings, showing 33fps in the Auction house.

Ran a dungeon and temp didn't go over 120F for one CPU Heatsink and 115 for the other. CPU fan at 703rpm.
