Linux - wireless at ipw3945

For some time, after upgrading to Ubuntu Feisty 7.04, my wireless wasn't working. After some research, it came out, that the kill switch is turned on, and it's needed this switch to be turned off, for the wireless to work. I tried different commands and things, but every time I was just close to making it work. These griefs were ended by an user in the ubuntuforums, named 'goranpop', who suggested, that two simple commands would give life to my wireless (here's the thread).
The computer is Fujitsu Siemens Amilo Pro v3505, the wireless driver is ipw3945abg, and the commands are (as a root):

modprobe fsam7400
echo 1 > /proc/driver/wireless/radio

This turned the kill switch (and the led) off, turning me into a content user of Ubuntu Linux.
