I have a toshiba 46H83 driven by an integrated 6150 over dvi.  I get
BIOS messages and all that fun stuff.

I have the same resolution problems for 1080i.  But for 720p I just
removed all of my modelines and let the driver/x/edid work it out.  I
have a bit of overscan but not terrible.
The 1080i thing is a apparently a bug in the nvidia drivers and how it
reads edid data from dfps.  If you search for 1080i on nvnews.com
there are a bunch of threads about it.  Someone found a crazy modeline
to make 1080i work, but it locks up the xserver if you try to use xv
or xvmc.  So for now I am sticking with 720p.  It looks good and I
spend less time banging my head against the wall.
