I have been using that very same SlimSCSI without a problem. I have one
suggestion:

> pcic0: management irq 10

IRQ for pcic is only necessary when you insert and remove cards, and,
then, only if you do not want to run the detachment/attachment commands
by hand. You might, then, change the pcic0 to polling by adding the
following line to your /boot/loader.conf (create one if needed):

machdep.pccard.pcic_irq="0"

This will free irq 10 for other use. You then change pccard.conf
accordingly, to give that irq preference.

These are not sharable.
