I sent a request for help on this problem earlier, but with no luck in
solving it. Now that I have some more information about it and a better
understanding I hope this problem can be fixed. I have a 10/100 fast
ethernet carbus card that uses the realtek 8139 chipset that I'd like to
use with FreeBSD. I have 5.3-RELEASE installed on a PIII Celeron in a
Compaq Presario Laptop. The card is reconized and the rl driver seems
to load, but fails to map the card's memory or i/o ports. Here is the
appropriate kernel messages:
cbb alloc res fail
cardbus0: Can't get memory for IO ports
cbb alloc res fail
re0: couldn't map ports/memory
cbb alloc res fail
rl0: couldn't map ports/memory
cardbus0: <network, ethernet> at device 0.0 (no driver attached)
cbb0: CardBus card activation failed
Intrestingly, it looks like two different realtek drivers are trying to
access it, re and rl. Can this cause a problem and is there a way to
determine the correct driver for it? I think rl is the one I need.
Here's pciconf -vl for the card:
none3@pci2:0:0: class=3D0x020000 card=3D0x813910ec chip=3D0x813910ec rev=3D=
0x10
hdr=3D0x00
vendor =3D 'Realtek Semiconductor'
device =3D 'RT8139 (A/B/C/810x/813x/C+) Fast Ethernet Adapter'
class =3D network
subclass =3D ethernet
Also, /dev/card0 does not exist, is this a legacy item from 4.x and
earlier. If so, then pccardd and pccardc are also no longer needed?
It seems like somewhere I saw a similar problem with another cardbus
card and the solution was to set some sysctl like allow_unsupported
something or another in the loader at boot.

I sense much NT in you.
NT leads to Bluescreen.
Bluescreen leads to downtime.
Downtime leads to suffering.
NT is the path to the darkside.
Powerful Unix is.
