Hmm, this might even be the best idea, I'll see if I can get
the time to write down how to do this. Remember though that
it is only possible to use the std clock rates, which probably
will result in some strange resulution.
For the adventurous look at the function set_mode() in syscons.c
that together with a description on how the videomodes are
stored in the BIOS will do the trick. I even remember seeing a little
util for DOS(I know...) that allowed one to play with the video regs
"online". That would give the values you need...

So much code to hack -- so little time.
