FWIW, this hardware should be supported 'out of the box' with the LAPTOP
kernel in FreeBSD 2.2.6.
BTW: does the FreeBSD 2.2.6. boot.flp contain the support
for the above hardware also?

This came up 2-3 days ago on this list, and the problem is that the IRQ
assigned to your card is actually in use by some hardware on your box,
but the FreeBSD kernel doesn't know about it. (A built in IR
port/sound-card, or something).
You'll need to hard-code the IRQ used.
I disabled the COM[1-2] and LPT1 ports (which free the IRQ's 4, 3
and 7) and tried to reuse all of these IRQ's for the 3C589D card
in the /etc/pccardd.conf file. The IRQ 3 didn't work at all
(the driver complains about a wrong IRQ mask) and the IRQ's 4
and 7 were attached via pccardd(8) to the card but with
slow network performance (ping delays of ~1.600 ms).
I checked the same BIOS setup with the Linux boot diskette
and the Linux cardservice uses IRQ 3 for the 3C589D and
after running ifconfig(8) for the interface all was fine.
I don't want to compare Linux vs. FreeBSD and the only
reason for saying that is: I can't imagine that there
is a problem with the hardware or IRQ values. Should I
dig into the kernel driver if_ep.c for that problem?
