OK.  I'm not sure I totally understand all this.  xvinfo on XF 4.2 on
ATI (both DRI and non-DRI) and NVIDIA all report "id: 0x32595559 (2YUY)"
as the first available image format.  Without the patch, only the ATI
DRI case has wrong colors.  The XF CVS patch may address the ATI DMA/DRI
issue, but what about the NVIDIA case.  Does this mean the NVIDIA X driver
is currently broken (reporting incorrect image format)?
