I experimented with an ATI card I had hanging around and with the Free
driver (ati, if I remember correctly, since it was a Rage 128), Xv output
with an interlaced modeline resulted in only the top half of the display
being shown (i.e. the output was stretched vertically).
I also tried with a Radeon 7500 and it seemed as though PAL output was right
on the edge of the clock it could output, resulting in discolouration around
the edges of the picture (that was about 10 months ago, with the Free radeon
driver which was around at the time).
The Nouveau driver might be worth a look in due course; I last tried it in
March 2008 without much luck on my GF4 MX440, because the version shipped
with my distro wasn't new enough to include Xv support.
