Yes, I use the fglrx driver. I can't get the open source one to work,
maybe because agpgart in Linux 2.4 doesn't support my chipset, so I have
to use the agpgart provided the fglrx driver.

Anyway, after applying Marcel Naziri's patch the YUY2 and UYVY spaces
work again. When he posted it back in January, the problem was that
there was no reliable way to detect whether the ATI or open source
driver was being used. One solution could be to just always shift the
DGA address down by 8MB. I'm sure all Radeon cards have so much memory
that it doesn't matter...
