Heh, I guess I have used madwifi too much :) 

I didn't even think of hostapd, for some strange reason I have always
thought it as an optional feature.

I couldn't find any instructions how to use hostapd with mac80211, so
here's what I did (for the archive):

o pulled latest wireless-dev#everything

o pulled latest hostapd from git

o compiled hostapd with these extra settings in .config:

CONFIG_DRIVER_DEVICESCAPE=y
WIRELESS_DEV=/home/kvalo/linux-2.6/
CFLAGS += -I$(WIRELESS_DEV)/net/mac80211

o edited hostapd.conf (wlan1 is my b43 interface):

interface=wlan1                                                                
driver=devicescape                                                             
hw_mode=g                                                                      
channel=5                                                                      

o started hostapd:

# ./hostapd hostapd.conf
