What would be a reasonable way to implement that? Use a SYNC counter
where the lowest bit describes field parity? Or maybe even the two
lowest bits for those external TV encoder chips which have extended
information about PAL fields? I guess those are not used on ATI,
but for example on some NVidia cards, and one probably should at
least do some planning to support the same standards across cards.
A SYNC counter would also give clients information about whether 
50 Hz or 60 Hz is used, and when the image changes.

Or extend Xv, and include field information with the data pushed to X,
and let the X server handle it?

Or maybe in some different way?
