I also just became aware of a tool that could help us fix the problem reading wlan state on your machine rather than just avoiding it. Please download the acer_ec.pl script from:

http://code.google.com/p/aceracpi/wiki/EmbeddedController

Then please execute the following sequences. Note that the page says that there is a possibility that the script could lock up your machine, so it's best to run it with all applications closed, etc.

Sequence #1:
  1. Start with a fresh boot (presumably wifi is enabled and working)
  2. Run 'perl acer_ec.pl regs > wlan-pre-rfkill'
  3. Run 'rfkill block <n>', whiere <n> is the index for the acer-wireless switch
  4. Run 'perl acer_ec.pl regs > wlan-post-rfkill'
  5. Repeat 2-4 above for the acer-threeg switch, changing the output filenames accordingly

Sequence #2:
  1. Start with a fresh boot (presumably wifi is enabled and working)
  2. Run 'sudo rmmod acer-wmi'
  3. Run 'perl acer_ec.pl regs > wlan-pre-hotkey'
  4. Press the wlan hotkey
  5. Run 'perl acer_ec.pl regs > wlan-post-hotkey'

Please attach all of the output files.

Thanks for all the testing! We should be just about done.
