when you are trying to trouble shoot problems with specific hardware
configurations it is generally helpfull to post a dmesg of your running
system to the list.  you can just type "dmesg" in a shell and paste the
results into your email.  it does sound like either your cards are broken
or have a chipset on them that is not supported by OpenBSD.
