everything else on the laptop is set to IRQ11. (well, enet, cardbus,
video). I tried using setpci to change the USB irq to something unused
(IRQ3).. but that didn't work (unless you use 'lspci -b' to show bus
view).. either way it didn't work in practice.
Using the dump_pirq program from pcmcia-cs, i get the following output:

If i'm reading this correctly, the board is wired up for USB to use irq
11, not irq 9...but everything wants it to use irq9. Without bios
support, what can I do? Is linux's interpretation of the ALi PIRQ tables
incorrect?
Other files of interest follow.. any feedback would be appreciated.
