The way I made extra interrupts available was by moving the interrupts on my
parallel cards to 11 and 12.  This freed up interrupts 5 and 7 to use with
other devices (like a mouse).  However, I had to do a hardware patch to the
parallel boards to redirect the interrupt signals.(actually, I had an EE 
friend do the rewiring to my specs).  I don't believe that most bus mouse cards
are able to generate interrupts on the upper bus with any jumper position.  If
you are interested in more details on how I got this working, send email and
I'll go into more detail.
