acer_wmi and rfkill

The 2.6.28 Kernel contains a patch for acer_wmi, which integrates it with rfkill.

Unfortunately, this has an adverse effect on suspend (at least for me) in that the wireless is switched off at some stage during the suspend / resume cycle. 

My solution is to create a /etc/pm/sleep.d/55Network file and add the following:

#!/bin/sh
# Stop the network before suspending

[ -f /etc/rc.d/network ] || exit $NA

KILL_STATE=/sys/devices/platform/acer-wmi/rfkill/rfkill0/state
case "$1" in
    hibernate|suspend)
        /etc/rc.d/network stop >/dev/null
        ;;
    thaw|resume) 
        if [ -f $KILL_STATE ] ;
        then
            echo "1" > $KILL_STATE ;
        fi
        /etc/rc.d/network start >/dev/null
        ;;
    *) exit $NA
        ;;
esac

Note: Stopping and Starting the network is necessary on my system using ndiswrapper. You may or may not need to do this depending on your wireless device.
