You set the irq for the management IRQ in the kernel config file. You
should set it to 11. It defaults to 10. You'll also want to delete
the machdep.pccard.pcic_irq line from your /boot/loader.conf for now.
Also, you may want to try this in polling mode, in which case you'll
want to remove the irq XX clause from the config file. That will free
up one more IRQ if you need it.

: Yes.
cardbus is completely broken in 4.0. There's no support for it at
all, and the dev/cardbus files doesn't even compile, they are too
green.
