[bwn] bcm4311 Acer Aspire One rf switch

[skydrome]

I have the same setup as this person here
http://forums.freebsd.org/archive/index.php/t-29407.html

the exactly problem is when issuing:
wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf

RF Switch LED on laptop blinks once and i receive message:
bwn0: firmware version (rev 410 patch 2160 date 0x751a time 0x7c0a)
wlan0: ieee80211_new_state_locked: pending INIT -> SCAN transition lost
bwn0: status of RF switch is changed to OFF
bwn0: please turn on the RF switch

Now the problem is is that the aspire one bios has no bios control for
explicitly en|dis|abling the rf switch, in fact, i cannot turn it off.
When i switch it, it remains on (light is on)

Ive tried editing if_bwn.c, removing the check for rf_onoff() but to
no avail, ill have to read the source more in depth.
I wonder what else i can do to resolve this issue.

Extra Info:
on linux (specifically archlinux), the rf switch doesnt do anything,
doesnt even trigger a acpi event. On fbsd no acpi event is trigger
either (debug.acpi.enabel_debug_object=1)
