PMODE/DJ doesn't reflect hardware interrupts to protected mode (it's 
explained in the docs that come with PMODE).  So if Allegro doesn't hook 
real-mode interrupt with a callback, your program might miss some 
interrupts.

Another reason might be the different PIC handling as explained in the 
PMODE docs.

Note that the above is purely theoretical; I don't know anything about 
Allegro.
