I was using a PCI NE2000 card with FreeBSD 2.1.6 (I'm now up to 2.2) 
and I needed to do the following to make it work:
1) Install the card
2) Use the software with the card to figure out what it's irq and i/o
   port are.  My card's software told me that it was irq 10 and i/o
   port 0xef80.
3) If installing for the first time, boot the disk.  If you are adding
   this card to an existing system, type 
	-c
   at the Boot: prompt.
4) Select the non-visual configuration if using the boot disk.  If
   booting your existing system, I believe that this is the default.
5) Set the i/o port and irq for ed0 by typing
	irq ed0 10
	port ed0 0xef80
   Of course, use whatever numbers your card's software gave you in
   step 2.
6) type q and press enter to continue the installation/booting.  Your
   card should work.

If you are adding this card to a system with the kernel source, you
can set this stuff up in the kernel configuration file.  There is a
line like:
  device ed0 at isa? port 0x280 net irq  5 iomem 0xd8000 vector edintr
which you can change to
  device ed0 at isa? port 0xef80 net irq 10 iomem 0xd8000 vector edintr
Recompile your kernel, reboot, and call it a day.

Hope this helps.
