I have a 2.8 Pro (late 2008, 5,1)
mine came with the most recent EFI and SMC firmware, the recent update reported that it was unneeded, and I confirmed i have version;
Boot ROM Version: MBP51.0074.B01
SMC Version: 1.33f8
and Nvidia
ROM Revision: 3343
I have been having Black screen /looping audio crashes since day one, in Vista 32, Vista 64, and OSX games.
at first I thought drivers were the issue, but of course later discovered that these are simply more of Nvidia's faulty chips.
here's a good site for everyone to read

Anyway
I have a G-Bar appointment tomorrow and will get a better idea of what my options are.
considering that most likely ALL the 9600's in these machines are defective, I doubt a repair/replacement will cure my woes, but I'll of course test and report back with my experiences on that.
all I want to do is play Fallout3 in peace!
