Ok, I got Cpu-Z fixed "sort-of" with 64-bit Vista... you reboot like you would for safe mode F8 and choose don't use digitally signed drivers... I know utilities do this also... Vista Manager or Tweak VI, not sure which one... anyhow heres the screen shot...
Like usual, he's all over the place.

I think Vista 64bit RTM will not allow unsigned drivers.
But I am running 32 bit Vista Business RTM and I have to say it is certainly NOT a warmed over XP.
