Right, my tv shows a 1920x540p modeline, but I can't get my FX5200 or
a Radeon I tried to work with such a modeline(don't know why the
Radeon didn't work, but I didn't try to hard either...). Once 8756
came out my FX5200 works fine with a 1080i modeline... It also works
with a 480p modeline that isn't in the EDID =) the worst part is that
its a 1080i native tv, which means until recently I couldn't feed it a
1080i signal =(
