I know you can control the screen resolution on the fly -- I don't
know if you can control the "visual" if it switches to/from true
color, but I suspect you can switch other things. Read the XFree
documentation for details, but XFree is capable of doing some cool
things.

Doom can't handle a true color visual? It *requires* a non-true color
visual? I find that hard to believe, but if it is true, the sources to 
Doom are available and should be *very* easy to fix on this (unless
they are playing colormap tricks to simulate animation :( )
