On many laptops, you are SOL.  You only have 1 interrupt line.

However, maybe, just maybe FreeBSD is being a ittle stupid in
assigning interrupts.  Check out http://people.freebsd.org/~imp/pir.c
to see if these devices can have different interrupts assigned.

There's nothing you can do about an0 and pcic0/1 having the same
interrupt.
