Isn't 480p potentially a computer signal?
480p is approximately (but not quite) standard VGA. 480P video would be 720x480 progressive, vs. 640x480 for VGA.
I wouldn't give up quite yet on getting the monitor to work with your GPU, but you'll probably have to craft a custom modeline for X.
DISCLAIMER: I don't do much X stuff either, but I know HD pretty much inside and out (I design video hardware for a living, and am currently working on a baseband HD card for PCI Express).
Your monitor will likely be happiest with a 1080i HD signal (details to follow). In addition to the basic scanning parameters, you may have to worry about colorspace. DVI is typically RGB, but the newer DVI derived specs like HDMI allow YUV in 4:4:4 or 4:2:2 modes. Since you indicated some VGA resolutions worked (but didn't quite 'fit') with the monitor, and you didn't mention the colors being all wacked, I'll assume your toshiba supports RGB.
There are a variety of 1080i HD signal specs, based mainly on framerate (24 Hz for film, 25 Hz for PAL countries, 59.95 and 60 Hz for NTSC countries). Good ol' American 59.95 Hz 1080i would have the following specs per SMPTE S292M:
Pixel rate: 74.25/1.001 MHz (apx. 74.176 MHz) Active H pixels: 1920 Total H pixels: 2200 Active lines: 1080 Total lines: 1125
A quick google search turns up the MythTV modeline database, which has the following entry that looks like it might work for you:
#ModeLine "ATSC-1080-59.94i" 74.176 1920 1960 2016 2200 1080 1082 1088 1125 Interlace
You might also want to try the other ATSC-1080-*i and ATSC-480-* modes listed on that page, since that's what your monitor claims it supports well.
