You're getting close. What, if anything, is on the irq line of
/etc/pccard.conf? That line lists available IRQs and, when running
with ISA interrupt routing, is where pccardd gets the IRQ to use. It
will try to use them without regard to something else using them.

Either add a line to /etc/pccard.conf (which you can cerate if it's not
already there) reading "irq 9 10" or change to PCI interrupt routing
which will allow IRQs to be shared. For PCI interrupts, the contents
of the irq line are ignored.
