I believe you are right.  The BIOS upgrade I ordered last week came in the
mail (just about the time I got your message).  After installing it (and
after about 2 hours of fiddling with the new BIOS settings, card ordering
and kernel PCI options) the BIOS-detected PCI conflict is gone and I've
gotten NetBSD to recognize all of the cards.  tcpdump actually sees traffic

However, both PCI-based NICs are interrupting on the same IRQ (see below).
Is that
a problem?
