Ok, "seem to have lost support" is about the vaguest thing you could
have said. I've killed people for less. Please explain in detail how
you arrived at the conclusion that the card was no longer supported.
Show us the dmesg output from your machine. Explain what you tried to
do and what results you observed. Don't just say "it doesn't work."
You've not going to help anyone that way.

FreeBSD 4.2 has a new driver for AMD PCnet/PCI devices, in particular
the 10/100 cards, because the lnc driver runs these cards in 16-bit
LANCE compatibility mode which really impairs their performance. Did
you check to see if a pcn0 device was detected? Did you attempt to
use it? If not, why not? If so, what happened?

You're soaking in it.

Should work with the ed driver, *provided* you get its I/O address set
correctly so that the ed driver will detect it. I haven't used one of
these since FreeBSD 2.x though.

Don't know about these.

Should also work with the ed driver, though you may have to turn off
plug and play mode using the SMC EZSetup utility.

If this is a 10mbps card, it should be an NE2000 clone, and will work
with the ed driver. If it's a 100Mbps card, it should work with the
rl driver.

I'd be happier if you told me whether the pcn driver works or not.
