I think I've worded that condition in a confusing way. All should be
well if you are using TV out.
I've been using the VGA to Scart trick, which requires interlaced TV
timings from VGA. Finding chip/driver combinations that can handle
that is harder. Many ATI chips now work if you use the radeon driver.
And development of the radeon driver is very active. I've had a Radeon
9000 work. I'm currently using an integrated X1250. I've heard that
an integrated HD3200 will work.
I don't know about 1080i. I don't have HD capability at the moment.
There's been a lot of talk of nVidia's drivers not supporting interlaced
output correctly, but I don't know if that applies to just VGA, or
also TV out. 1080i via HDMI might be fine. Don't really know.
