Hi Martin,

I have tried your patch against 2.4.0-test7 and confirm that it works
beautifully - the device 3C905C-TX behind the bridge is recognized and
working just fine.

Hugh and Simon, this means you can use your docking stations now.

Martin, however, there are now some interesting PCI-related messages on
boot which didn't happen before - I attached them for your analysis, if
you are interested.

Regards,
Tigran
