Status update: It lives.
I re ran the install scripts for the drivers and it seems to have worked, then again it might have just gone away on it's own. I have no idea. The updates were courtesy of the auto update tool, I had run it the day before and it had pulled down a couple of updates for the packages I got in 9.04.
The Display is still messing me about and telling me it cannot save the file that's there and when I boot the first screen the HDTV sees is the log in one, pressing esc before that shows a blank screen with a "out of range" message. Once it does get to the loading screen it does switch to 1024x768 or something close and works fine, with the caveat that the text size is about 1 or 2 pt, completely unreadable, until I've logged onto the desktop.
As for going away from Linux, i'd rather not. Windows isn't built for what I want this to do.
