     If you're doing something like this, you might want to consider using
NASM for your driver.  If you don't know, NASM is an Intel-syntax (as
opposed to AT&T) compiler that can output to DJGPP-format COFF files. 
I've got a tutorial that includes a step-by-step mouse driver at:

There's some supplimentary source at:

     Of course, you can always d/l the Allegro package and see how the
mouse routines are done there, if you want to use AT&T syntax.
