No hack at all, I agree. MiNT hooks onto a BIOS vector. TOS BIOS jumps to
this vector, and provides scancode as an argument.

Nevertheless, some problems remain:

1) not all TOS versions provide this vector.
2) not all TOS versions provide AKP (Allan K. Pratt, if I remember
correctly, aka Alternate Keyboard Processing) keyboard handling code.

So ideally we must totally replace keyboard routines whenever
possible/necessary, so that MiNT would behave similarly on different
computers.
