I have a Toshiba 26HF84 tv and I drive it at 720p over HDMI from the DVI
port of a MSI Geforce FX 5200
It took me a while to get the right xorg settings (posted below),
because the tv's PnP data only allows 640x480 @ 60Hz. Eventually I found

I don't get anything on my tv until X loads with this card, but with an
eVGA PCIe geforce 6200, it displayed the bios & kernel screens just fine
I now leave my s-video plug hooked up to the tv as well, and switch tv
inputs to view my bios & boot screens, as it is rare that I need to
I have tried a few times to get 1080i, but I only have standard def
input via a pvr-250, so it doesn't gain me anything right now.
I just noticed that the 720p modeline is missing from my monitor
section, it must be that the newest nVidia binary driver(9629) can do it
automagically, and the setup deleted it.
I have the service mode for this tv as well, and I think it might work
for yours. email me if you want it. I was able to reduce the overscan
slightly, but the sides of the raster are really ugly on this tv, so I
make do with Mythtv's GUI size adjustments.
here are the important sections of my xorg.conf
