Yes - I tested with 3.2.0-rc4-rt5 (and it actually is an RT kernel this 
time - see below!) and with the Ethernet interface down, it seems to be 
working properly.  Even Pure Data didn't cause any crackling or 
stuttering (other than when starting up).

What next?  Should I try moving the Ethernet card to other slots and see 
if anything changes?

Thanks,
