Yes, you can.  I built a little GUI installer a while back using Qt/Embedded, 
which supported an option telling it that while the fb resolution was 
640x480, it should only use say, 580x420.  It worked fine.  

I really don't know if X supports this though, though there is no technical 
reason I can see that you can't do it.  You basically want to say "Set the 
res to X x X, but only use the innermost Y x Y pixels".  I seem to recall the 
people fiddling with the hdtv side use 'dead pixels' to adjust this, but 
unfortunately, I'm not knowledgeable enough about X to be able to say.
