Notes

[1] I've upgraded the BIOS to version 1.40.T1 (02/18/2005), which enables the software wireless switch by default. With older BIOS versions the acerhk kernel module is probably required to enable the software wireless switch, see below for instructions how to do this.

Loading acerhk kernel module and enabling wireless

This module can be loaded with the modprobe command: 

 $ sudo modprobe acerhk

To ensure that the acerhk module is loaded after the next reboot add it to /etc/modules as follows: 

 $ sudo -s
 # echo acerhk >> /etc/modules
 # exit

The software wireless switch can now be enabled with the following command: 

 $ echo 1 > /proc/driver/acerhk/wirelessled

After configuration through System > Administration > Networking, the wireless card should now work

To enable the wireless switch on boot add the echo command to the /etc/network/if-pre-up.d/wireless-tools script which is called before the wireless card is configured. Edit the pre-configure script 

 $ sudo editor /etc/network/if-pre-up.d/wireless-tools

and add the echo command as shown in the example below 

 #!/bin/sh

 echo 1 > /proc/driver/acerhk/wirelessled

 IWCONFIG=/sbin/iwconfig

 if [ ! -x $IWCONFIG ]; then
  exit 0
 fi

With these changes the wireless card should be enabled automatically after a reboot.

To disable the wireless card with the software wireless switch use the following command: 

 $ echo 0 > /proc/driver/acerhk/wirelessled

Acknowledgement

Thanks to [http://heim.ifi.uio.no/~krisvh/linux/cl56.html Linux on Compal CL56] from Kristian Vedvik Holm for the information about enabling the software wireless switch.
