Hi Warner! and thanks for taking the time to reply to this during the holidays! 

The card in question is a '3Com Mehahertz 3CXFE574BT', it's a 10/100 X-Jack card
(very handy, no dongles), and other anything that will recognize it as such, with the exception
of FreeBSD (multiple flavors, see below):

I've used the card successfully on my Thinkpad 390X with the following results:

MS Windows (All Flavors): recognized correctly, with 10/100 settings available
NetBSD (1.5x, 1.6x, NetBSD-current): recognized correctly, with 10/100 settings avail.
OpenBSD (2.8 - 3.4): recognized correctly, with 10/100 settings avail
FreeBSD 4.8: recognized as '3Com 574BT' , only 10 Mbs settings available
FreeBSD 4.9: same
FreeBSD 5.0: same
FreeBSD 5.1: same
FreeBSD 5.2: same

I determined (in the 'BSD's) if 10/100 settings for the card were available by doing the following:
'ifconfig inet ep0 10.0.1.25 media 100basetx mediaopt full-duplex', if it exited correctly, I knew I
was in good shape.
However, the same command under the freebsd's would generate 'SIOGETOPT:error' or something
to that effect. Also, the ep (4) man page makes no reference to the ep driver having anything but 10 mbs
settings.

Now I'm confused :( I really want to install freebsd next to winxp on this laptop (net's nice, but not enough software,
and open has it's own quirks, that beyond setting up a bastion host, I'm unfamiliar with, and linux, is for me, not a
real option).

again, thanks! If you need any more info, please let me know, I'll get it to you as soon as possible.

Eric
