I blacklisted the acer-wmi module in Natty and rebooted with the enabled
hw-switch.

Disabling & reenabling the hw-switch does not unblock the "hard block".
Loading the acer-wmi module and toggling hw-switch does not unblock the
device neither... ??? (though this works if acer-wmi is loaded during
boot as shown in previous comments...)
Btw, if you want me to test your 3.0... kernel for oneiric, please
provide a 32bit version as this is all I have :-)
