The "setup" program accompaning the card didn't find the card.  It
says in the docs that the card is configurable by jumpers, but the
card doesn't have any. It says in the docs, that the card is
configured to IO-Address 0x300 and irq 5 if not changed by PnP
software. This was not true. The card was simply inactive.  So I
gave up on ISA-PnP.

And switched to PCI-PnP. 
At least their setup.exe let me configure the IRQ(5), and showed
me that the IO base is fixed at 0x4000. So I put these values in
plan9.ini rebooted and -- it worked! At least on the plan9 side of
my two computer network. The other end now misses a PCI-ethernet
card :-)

Autoconfiguring PCI-versions of clone cards would increase the
usability of Plan 9.

Thanks for the replies,
