I tried that earlier, but got the same results.
# ifconfig wlan0 hw ether 11:22:33:44:55:66
SIOCSIFHWADDR: Cannot assign requested address
Even trying to assign an IP address doesn't work.
# ifconfig wlan0 inet 192.168.1.105 netmask 255.255.255.0
SIOCSIFFLAGS: Cannot assign requested address
Here's how my modified board-omap3beagle.c looks like, for the mainline wl1271 drivers. (The modifications for the board file and the board-wifi for the TI proprietary drivers are different, and that is a separate issue that I'm working on in parallel for android-2.6.32 kernel).
