With kern.* sent to /dev/console in syslog.conf, I don't see anything on
the console between when I do ifconfig eth1 up and the lockup (most of
the time, I don't even get my command prompt back before I lock up).

I only have one other card.  It's packaged as a "Hawking Technology
PN672TX," but is identified by card services as a "Linksys EtherFast
PCMPC200 v2" - is this one worth testing with?  I've tried just sticking
it in and seeing if it works, but didn't even get anything in ifconfig
-a for eth1 after I booted with it.  What other output can I send you
from this test?

Any suggested versions to try? 

I don't know if this is worth mentioning, but with the Netgear card, I
only hear the "high" PCMCIA beep at boot.  With the Hawking's Card I
hear both beeps (but still have the symptom above).  With either card,
if I insert or remove the card with the system running, I get a hard
lock. (These may be unrelated to the problem, I don't know).

Thanks again for your help!
