How can I make an inverse virtual screen?

How can I make an inverse virtual screen?

[John Zielinski]

I just booted my linux test box hooked up to my HDTV.  The fb console 
started in 1920x540 mode.  Sweet!  The problem however is overscan.  Is 
there a easy way of doing an inverse virtual screen?  I want the virtual 
screen to be smaller than the real screen.  I was thinking to look into 
the way the logo is handled as that does the top of the screen and 
somehow make it do the same for the sides and top.

Any other suggestions?

John

Decrease the resolution and increase the sync margins?

The HDTV probably will loose sync then. They are extremely fussy about 
signal timings. I'll give it a shot however.

Besides, I want to use the same timings in X for video playback where 
using the whole screen is a good thing.
