802.11[b] does not support 802.1d bridging while in station
(Infrastructure / Ad-Hoc) modes due to how the AccessPoint directs
packets to the stations. To solve this shortcoming, you can either do
PtP HostAP with WDS, or use a vtun tunnel between the client and AP (or
the router behind the AP).

I have this working fine here. With two ISA Vadem + 2 orinoco silver
card and orinoco_cs driver. With hostap driver I only know that is
possible (2 LG PCI Card had been configured correctly in my box), but I
did not test in a production environment, as I make with orinoco_cs.
