: You must use IRQ 9.  What do you mean "which doesn't work on this

: interrupts, and those are shared between the cardbus bridges and the
: cards taht are inserted into them.

The PC-Card and CardBus busses *should* use IRQ 9, and they do.
However, the card itself should not use IRQ 9 ... it needs IRQ 10
(assigned to disabled IrDA) or 11 (free), because it doesn't work with
a shared interrupt.

Under 4.8-RELEASE, the installation routine gives me the option to
start pccardd, and i can further request it to start as follows:

  pccardd -i 10 -i 11

which will only let inserted cards get IRQ 10 or 11.  This works fine.
I need to know how to limit the IRQs assigned to inserted cards under
5.1, since the device hints don't seem to work.

: : | 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.

(See above).
