It shows up on /proc/interrupts as IRQ 9.  There are no conflicts
there.  But yes, you're right, my PCI video card is IRQ 9.  Argh.

The box advertised that it would let me do 'internet phone' stuff --
the IW part doing one direction and the SB part doing the other with
respect to full duplex, or something like that.  Ah well.  Maybe
there's some other way to do that.  I'll try what you suggested.
