Hello
I''m trying to get a Broadcom BMC4306 wireless pci nic
to work on domU. I manage to get the nic working on
dom0 using the bcm43xx module and firmware extracted
with the bcm43xx-fwcutter tool. once pci hiding is
applied the nic shows on domU but modprob''ing the
module gives the following error :

Segmentation fault
I suspect the fact that the card appears on 00:00.0
instead of it''s original location might have something
to do with it. Is there any way to set the ''mounting''
location of pci devices in domU ?
any help would be appreciated
dom0 runs debian etch with a 2.6.18-4-xen-686 kernel.
