You must use IRQ 9.  What do you mean "which doesn't work on this
laptop?"  The reason it is forcing IRQ 9 is that it is using PCI
interrupts, and those are shared between the cardbus bridges and the
cards taht are inserted into them.

: | cbb0: <RF5C475 PCI-CardBus Bridge> at device 10.0 on pci0
: | cardbus0: <CardBus bus> on cbb0
: | pccard0: <16-bit PCCard bus> on cbb0
: | pci_cfgintr: 0:10 INTA routed to irq 9

If IRQ 9 is the wrong thing to route here, then you'll need to add a
hint to route the right thing.  If your laptop had ACPI the following
would work:


but I don't see that you have acpi in the dmesg.  So you need to use a
recent -current snapshot which supports a little better control of
which IRQs get used.

: | current process        = 6 (cbb0)

I'm not sure what is causing this.
