Ah ha, interesting.  I noticed it, because testing both the parallel 
port and NE2000 ISA card, I had to avoid that IRQ.  The parallel port 
card had physical jumpers I set on it to get around trying to use IRQ3, 
and the NE2000 Card you *have* to know the IRQ.  Can't use the 
ether=0,0,ethX line on the kernel, because if the kernel attempts to 
probe for IRQs, it runs into that panic.  Enabling it didn't seem to do 
anything bad either, except that odd message which sounded pretty weird 
for a kernel.
