Well, other devices are seeing it, eg other Atheros devices and intel
IPW2200. So somehow i doubt it is not sending beacons.

CH has no such regulations...

I hacked the madwifi driver a little, to disable the wme_ie and the
ath_ie IEs in the beacon and probe response messages. Only then did
the b43 device list the Atheros device in its scan list. However i
could not get it to associate. Authentication always failed. The b43
driver gives error messages and the MadWifi driver never received the
Authentication request messages.
In the end i gave up. I have another machine with an ipw2100 card
which worked first time and i don't see any point using the B43 device
when it causes me to much pain.
