I think the non-fullscreen DGA driver is just a hack for when
you can't set the mode requested.  Some sort of emulation for
that may be to try to set the next higher mode which is present
in the X config file.  But I don't think this is very useful
behaviour anyway -- the way the rest of Allegro works is to fail
the mode set if the mode is not available.
