I can say that here (c2q q6600, 8800gt) for the samples that work, almost 100% of the decoding is offloaded.
When playing a 1080P sample of Gladiator, cpu usage sits at < 1%. Compare that to ~80% without the vdpau.
VERY few movies actually work, though I'm sure this will be remedied soon.
I think the possibility of smooth 1080p playback with a VERY lightweight CPU and a decent nvidia chipset >= 8xxx is a reasonable one.

The reasoning for this is that apparently only one H.264 "profile" has been accelerated to date. I believe I picked that tidbit up from the Pharonix testing or from one of the posts in their forums that naturally I cannot find at the moment. From the sounds of it they accelerated one profile as an example and are maybe hoping others will work out patches for others? I believe the max profile was 4.1? I'm not "up" on the nomenclature but am pretty sure that was what I'd read and that hopefully more will be coming as people tune up on this? The ffmpeg guys sound a bit critical of the patches <shrug>
