This looks a _lot_ like the problem I had with ep0 and a 3c509 card on
a 386 at work.  The machine sat there for ages, until I scrounged an
SMC card and switched to ed0 - as I've been using if_ed here for about
a year without problems.

It didn't work!!!

After checking the jumpers on the card and trying a few different
kernels, I _eventually_ had the bright idea of looking at the CMOS
setup...  sure enough it had all sorts of shadow ram enabled.
I disabled everything along those lines and hey, ed0 fired up ok.

I now believe though I have not yet tested it, that if_ep would have
worked fine... 

Just today I installed a kernel with the bsdi ipfirewall code added
in, it works fine, so I might try putting the 3c509 back into it, and
see if I can get it to work.

Anyway, have a look at your cmos setup.
