Xorg log with 'Option "ModeDebug" "on"' in xorg.conf

< malc0> Yoe: for now, I think you need to file a bug at bugs.freedesktop.org,
product xorg, component drivers/nouveau, saying we suck at interlaced modes on
digital, attach an xorg log, and note that simply allowing interlace doesn't
work.

When running nouveau with my laptop connected to my HD TV (Apple mini-DVI ->
DVI -> HDMI -> TV), xrandr detects two modes: one 640x480, one 720x480. When
using MacOS on the same configuration, it detects 1920x1080 at 50 (which is
reported by the TV as '1080i/50'), 1920x1080 at 60, and 1344x756 at 60 (both reported
as 1080i/60), though only the first (1920x1080 at 50) displays properly on the TV.

I should note that the 640x480 and 720x480 modes do create an image, although
it only uses the middle part of the TV and stretches the image vertically.
