Feed the developers beer so they fix up the code? 8-)

Seriously, this is a shortcoming of the Indy/Indigo2/Challense S/M code...
the interrupt handling isn't flexible enough to share interrupts between
devices and even if that *did* work, I'm not sure more work wouldn't be
required to get the Mezzanine SCSI/ethernet board running (ether may be
easy, SCSI uses a different chip for which apparently *NO* docs exist).

It's on my list of things to do, and I'm going to have to re-write the
O2 interrupt code anyway, so I'll try and do that in a way that the IP22
machines can also benefit.  OTOH, I've had little free time for hacking
lately, so I'm not promising any dates in the near future 8-)
