You mean the switch is off, and wifi should be on? What happens if you
switch it the other way round?

The patch is attached to this bug, and the full package change is

http://launchpadlibrarian.net/27776744/hal_0.5.12%7Erc1%2Bgit20090403-0ubuntu2_0.5.12%7Erc1%2Bgit20090403-0ubuntu3.diff.gz

It only changed the shell script which gets installed as
/usr/lib/hal/scripts/hal-system-killswitch-get-power-linux, so if you
want to hack on this, you don't even need to change packages, you can
just edit it inline.

Thanks for having a look!

Yes. You could e. g. downgrade hal to the jaunty final version with

  sudo apt-get install hal/jaunty

The other packages like libhal* can stay updated.
