Not sure if that helps anyone tracking down the cause; to me it appears to be a problem between the NVIDIA driver's OpenGL implementation and SDLs fullscreen - weird that it doesnt show up on the other 8x00/9x00 iGPUs though!
BTW, I had the very same problem with the refresh rates on an older 7050 based motherboard.
I switched to the 8200 for VDPAU.
