As you found out it only works in Vista (and will only ever work in Vista and above), it also only works with the 9800GTX, 9800GX2, GTX 260, GTX 280 with HybridPower mode.

I use it on my system, and must say its a pretty fantastic invention. The GPUs shut down *completely*, the fans don't spin anymore. Much less heat, quieter (slightly), and significantly lower power consumption. The HDMI output is also automatic which is pretty cool. Basically I hooked it up to my TV without turning the PC off or anything, and I could set up the correct res straight away and sound was routed through HDMI.

Sorry if I'm gushing a bit, but I am so impressed with this chipset. Rarely does a chipset cause more than a slight 'oh really?', but this one has some very underrated features because its for AMD instead of Intel.
