Weird VRAM reading

[I'mAMac]

Ok this sort of just threw me off. I have the 330m gt with 256mb of vram but when I go to check how much I have on my computer it is showing 1.1gb VRAM Is my comp using the leftover RAM not usable by the 32bit OS (Win7) and tricking itself into thinking it has extra VRAM?

I had the same thing happen on my mid 2007 mbp. It was reading my 8600m gt with 128mb of vram as having 512mb, i figured it is probably just reading some shared system/video memory somewhere.
