It won't work out of the box either (it uses only v4l read calls and doesn't support mmap, it assumes a capture size of 352x288 which this camera does not support etc).

As far as I know they have not been integrated into the Xfree tree. I believe there were some disagreements about extending the Xv API since GATOS added some extentions to support the AIW video capture cards. I suppose someone could try and submit a patch again and see if they'll take it. Also there is some work on a new XvMC interface that would allow for extended DVD acceleration.

It definitely is - at least if you use the XFree86 CVS tree with just
the ATI video extensions imported from Gatos. I've used the YUV
hardware for half-accelerated DVD playing ("half-accelerated" only
because the chip can really do MC too, but ATI doesn't document how to
do it, so it only does the YUV conversion).
I've not figured out why the ATI Xv stuff from gatos seems to not have
made it into the XFree86 CVS tree - it works better than much of the Xv
stuff for some other chipsets that _are_ in the CVS tree.
I imported it into the XFree86 CVS some months ago, it was trivial. I
don't have the patches lying around any more, though. I can try to
re-create them if anybody needs help.
