Bug Description
SRU Justification
Impact: The wlan on the Acer Aspire 1830 always has a soft block applied due to incorrect values read from the BIOS on periodic updates.
Fix: Backport patch that makes this model use WMI events to update rfkill states instead of periodic polling. Data in WMI events accurately reflects the status of the blocks. The backport results in a wlan soft block when pressing the touchpad hotkey, so also include a fix to only update rfkill states when wireless hotkeys are pressed as well as a trivial patch to support the wlan hotkey on this model.
Test case: Verify that wlan soft block can be removed, wlan hotkey functions, and touchpad hotkey does not affect wlan on the affected model. Tested on LP #771758.

On my Acer Aspire 1830-3595 I have the following situation:
after installing natty wifi won't work, the wifi is soft block when checking with rfkill
the solution was blacklisting acer-wmi module

It appears to be a very common issue that acer-wmi blocks wifi (Broadcom and Atheros at least). Should this be merged with similar reports such as bug #668234?
