since u have allegro source files , just check out the allegro 
src/djgpp/keyboard.c for their keyboard isr.

i don't get it. 
if u have u'r own keyboard isr installed, then it gets called even
when ctrl-break is pressed ,which does not result in program termination.
Thats why in allegro u have the three finger flag (ctrl-alt-end) as an
exit combo for emergency purposes (ctrl-alt-del in dos !! ).

if u still cannot get the keyboard isr working , then mail me.
i can send u a copy of my keyboard handler, which i wrote for an old vga 
game library.

if u do not want to write u'r own handler but just want a bunch of
functions that take over the keyboard directly , then u could use the
libkb library by Markus F.X.J Oberhumer available at
ftp://x2ftp.oulu.fi/pub/msdos/programming/libs
or the keyboard functions by Martynas Kunigelis 1996 - he has an asm and a
header file , ( got it with my installation though i don't know from
where they can be got now) somebody else who knows from where they can be
got , please do respond.

all the best :)
