Could you apply the patch above, and test again?  I think I've fixed
most of the problems, but I'm in a hurry.

The patch also steals console switching signals from SVGAlib, so
Allegro gets to do that itself.  Not sure how stable it is, though.
(i.e. needs more testing :)

Will not work with the banked version of the driver (but shouldn't
crash now).

Crashing because it was trying to set a mode X mode.  The driver has
been editted to not try mode X.  Use the mode X driver for mode X
modes! :)

Sub-bitmaps were a problem.  Not anymore.

demo has worked all along for me...

I don't have that problem much now.  I don't think I could be bothered
fixing it myself, but I think it *might* just be an SVGAlib problem.
Does it happen with other SVGAlib programs? (not including GGI ones
though, 'cause they cheat :)

Thanks for the bug reports.
