Just for an experiment, try configuring your BIOS to 'reserve' IRQ 12
for a (non-existent) 'legacy ISA' device. That is, what happens when
you effectively force the BIOS to assign IRQ 5 to the NetMos card? Do
things start working again? It *sounds* like there is some sort of
'bug' in the parport driver that causes it to get confused when it sees
an IRQ of 12 associated with a parallel port. Or something like that.
