On mine, IRQ 11 is only showing up as USB-OHCI.  Seeing as when I load
the driver it complains that it wants IRQ10 and eth0 has that, I set
IRQ10 to be reserved for ISA cards (I do have an ISA SoundBlaster16,
which is set to IRQ5.)  The NIC caught IRQ3 at bootup, which is fine
because i have my onboard serial controller disabled (don't use it for
anything, so why bother taking up resources? =))... Here's what I see in
/var/log/messages now...

What the heck?!?!  Now it wants IRQ 3????!?!?!?!?!  Why is it that the
IRQ it wants is always the IRQ that the NIC has??  Surely this has some
significance?
