After doing a little research this appears to be a known issue. The
kernel appears to not be able to differentiate between hardware
killswitches and software killswitches, hence the conflicting dmesg
information and actual configuration. It should be noted this is stuff
I have observed and no documentation seems to be around to prove or
disprove. While the LED"s don't seem to light up appropriately, if you
do a:

'echo 2 > /sys/bus/pci/drivers/iwl3945/0000:0c:00.0'

the Fn + F2 should appropriately activate and deactivate, however as I
mentioned, at least on my laptop the LED doesn't work.
