Got it. This would be the ultimate connection for my application. I'll
try to find a linux-friendly video card with DVI out. What does this
mean if I buy an HD receiver later on? I only have a single DVI input
on the TV. Will I have to buy a DVI switchbox or something?

Something like this should work, right?

By the way, I have used videogen to write mode lines before. Seems to
work pretty well:

Ted, thanks for the brain dump. This is _very_ helpful and gets me
pointed in the right direction. I appreciate it! I'll post my solution
to the list for archiving.
