** Description changed:

+ 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.
