Quite recent. I just updated it the other day (Friday/Saturday),
here's a 'uname -a':

FreeBSD pilgrim.magda.ca 5.0-CURRENT FreeBSD 5.0-CURRENT #0: \
	Sat Apr 26 00:02:46 EDT 2003     \
	dave_at_pilgrim.magda.ca:/usr/obj/usr/src/sys/MYKERNEL5  i386

When I insert the Xircom card I get the following:

  cardbus0: <network, ethernet> at device 0.0 (no driver attached)
  sio4: <Xircom Cardbus modem> port 0x1000-0x1007 \
    mem 0x88002000-0x880027ff,0x88002800-0x88002fff \
    irq 11 at device 0.1 on cardbus0
   sio4: type 16550A
  cbb alloc res fail

Investigating further, it seems a little while ago I took out the
dc(4) driver from a kernel config file. Since I usually use my
wireless network card (wi(4)) I didn't notice.

If I load the if_dc.ko module I get another interface listed when I
run 'ifconfig'. However, even if the module is loaded, when I pull
the card it still panics.

If I install the if_dc.ko module (and miibus) then the Ethernet card
is recongized for what it is. I do still get the line "cbb alloc res
fail". A 'trace' produces similiar output to the one I've aleady
posted.

Dmesg(8) output:
