Solution to all having this problem with the random freezes:
Follow the instructions in this macrumors post very carefully. It shows you how to downgrade from firmware 1.7 to 1.6. It isn't authorized by Apple, but is essentially what you would be going to the Apple Store to beg them to do (while they deny every word you say).

I have just done this on my brand new 13" unibody MBP with Snow Leopard and the problems have ceased.
After doing this, be sure to avoid applying the 1.7 EFI Firmware Update that will reappear in Software Update. Apple needs to release a real fix for this, already.
Good luck.
This is not a solution, this is a band-aid.
What you're left with is a half-speed SATA interface. Not an issue with traditional hard drives, but certainly an issue with modern solid state drives (and will only become more of an issue in the future as SSDs become more popular/affordable).
I would highly encourage anyone who lives near an Apple Store and who wants this band-aid applied to let them do it. If firmware gets borked in your hands, you may find yourself holding a nice, rectangular, voided-warranty brick. If it gets borked in Apple's hands, they are responsible to fix it.
