BCM4318KFBG not recognized by b43

[Daniel Klaffenbach]

Hi,

I just got a new Mini-PCI wireless card which does not seem to be
supported by b43 yet. On the chipset it says "BCM4318KFBG". I suspect
the vendor id of the card is causing trouble - it is 14a4 (GVC/BCM
Advanced Research) instead of the usual 14e4.

I've already tried to force the b43-pci-bridge to use this device, but
it resulted in a kernel Oops (I don't know if that made sense anyway):

Disabling lock debugging due to kernel taint


The full dmesg output of the device is available at http://pastebin.ca/1968330.

Is there anything else I can do to get the device to work? I'd be
happy to test any patches but please keep in mind that my distribution
(OpenWRT) requires me to use Linux 2.6.34 at the moment (which is the
most current version for BCM47xx in OpenWRT trunk).


Regards,
Daniel
