Jarod Wilson reported last week that there's SiS video card that's 
capable of putting out 1080i; no other card that I know of is, at 
present, though nVidia promises a driver update to enable interlaced 
modes in March (they've made this promise before...)

The rest of us are using 1920x540p or 960x540p modes, whose timing is 
the same as 1080i.  Do some searches in the archive for previous 
discussion.  I personally prefer 1920x540 because the video looks better 
(though the menus look somewhat weird); some prefer 950x540 because the 
menus look better (though you're tossing half the video resolution; 
realistically, though, most current display devices can't really resolve 
it anyway).

I have also placed a thoroughly-hacky solution into my own codebase that 
uses 1920x540 for video, and 960x540 for the menus, using the xrandr 
command.
