Nope. USB is just one of the devices on IRQ 9.

Hmm..

Odd. the cardctl info you asked for is:

ident:
Socket 0:
   product info: "Intersil", "ISL3890", "-", "-"
   manfid: 0x000b, 0x3890
   function: 254 ((null))

info:
PRODID_1="Intersil"
PRODID_2="ISL3890"
PRODID_3="-"
PRODID_4="-"
MANFID=000b,3890
FUNCID=254

config:
Socket 0:
   Vcc 3.3V  Vpp1 3.3V  Vpp2 3.3V
   interface type is "cardbus"
   irq 9 [exclusive] [level]
   function 0:

They didnt. See:

http://hibernia.jakma.org/~paul/prism54-cvs-errs-nowep-pirq-acpibalance.dmesg
http://hibernia.jakma.org/~paul/prism54-cvs-errs-wep-acpibalance.dmesg
http://hibernia.jakma.org/~paul/prism54-cvs-errs-wep-biosirq.dmesg
http://hibernia.jakma.org/~paul/prism54-cvs-errs-wep-pirq-acpibalance.dmesg

The biosirq case didnt work at all iirc. In all other cases, it dies 
pretty quickly on tcp traffic, eg ttcp, however as before it will 
happily pass ping floods of 1500+ byte ICMP packets, with 0 packet 
loss (which is strange).

Why does ICMP traffic not lock it up, but tcp does? (havnt tried ttcp 
in UDP mode yet..)

Hmm, possibly.
