Seems, that even Riva128 supports YV12, but it isn't supported for
overlaying :(

IIUC, current X11 CVS contains two drivers: one for DMA blits,
supporting YV12 (haven't tested yet) and one NV10+ only,
which doesn't use blits. BTW: Also, there is overlay driver in DirectFB,
but it uses same registers, as X11, so I suppose it's NV10+ only, and I
dunno, if (and how) it works.

I hope, I'll buy GeForce* card next month, and after that I'll try to
play with nvidia_vid again :)
