Well... I think it doesn't make sense to write such an interface. Allegro is a
self-contained library in every aspect and writing an interface to SVGAlib
would be just creating a new front-end. Allegro has completely different model
of driver structure. What you should do is to isolate the parts tightly M$-DOG
related and re-write them Linux-like.

 >2) rewrite keyboard functions
An easy one - you might use libkb. Or even it might not be necessary to change
the keyboard handling routines of allegro. AFAIR, Allegro installs hw int
handler for keyboard? If so, then, as long as PC platform is concerned, you
are in home with what you have in Allegro. If, however, you want to use
Allegro also on other hardware platforms then you have to create an
independent interface to UNIX kernel's kb handler.

That for sure.

Do you have Linux sources? Take a look at them and you'll know how to do that.

As with any port there probably will be a lots of problems. Memory issues may
be ones to give you a major headache, possibly file access functions.
