I have not experienced the flickering, blinking or garbled graphics described in the two links you provided.
Marc, that's not you.
If you read the thread, you'll see that a hard distinction has been made early on:
The OP has a frozen mouse pointer. This freeze turns out to be GPU related in some sort. With or without garbled screen pixels, depending on where exactly the GPU is broken. In some cases (as mine), waiting 15 minutes or until display sleep helps.
You have an unfrozen spinning mouse pointer. This isn't what this thread was created for. But it seems that a couple of people seeing this now post here anyway. The unfrozen spinning mouse pointer seems to be related to the SATA disk subsystem in some sort. Sometimes, the freezes only persist for a minute or less.
Apple addressed the latter bug in the EFI 1.9 firmware update. There is a knowledge base article about it, read here: [http://support.apple.com/kb/DL1098] . Newer MacbookPro 15" 2010 ship with EFI 1.9.
Your problem may be a sign that this EFI update didn't heal all your problems.
Please check if:
1. Your Boot ROM Version is MBP61.0057.B0C (which means EFI 1.9)
2. Your Serial-ATA Negotiated Link Speed is 3 Gigabit (mine is, Apple only ships 1.5 AFAIK).
