Okay.  I will again try your suggestions, at the end of this message.

I will try with 2.6.32 also; see below.

Okay.  Following is another attempt with 2.6.30.  With 2.6.32 the results are 
identical.

## Return to original MAC
# ifconfig wlan0 hw ether 00:21:91:01:11:6f

## Add bssid line
# echo "bssid=02:21:91:01:11:6f" >> /etc/hostapd/hostapd.conf

# hostapd -dd /etc/hostapd/hostapd.conf 
Configuration file: /etc/hostapd/hostapd.conf

I don't see any other debug information from dmesg.


Now I will try out compat-wireless with 2.6.32.
