It does something similiar here (VESAfb driver), nothing happens after
trying to change the mode -- the programs seems to stop, BUT: pressing
escape quits, and console switching still works, so it is still doing
_something_.

I never really wrote the fbdev target with multible modesets in mind, so
there could be some bad assumptions in there somewhere.

Another thing, the fbdev target's checkmode() doesn't work, so monitest
shows the message "Set may not fail!!", but I don't... OOOH, bad things
will happen if the program assumes that it DID succeed.  Are you sure
the new mode you were trying to set was possible ?

Cheers,
