Hi,

unfortunatly the issue has not been fixed in the latest upstream kernel. The kernel version I used to test was:

$ uname -r
3.15.0-031500rc8-generic

For the test I ran acpi_listen and toggled the switch numerous times.

Out of curiosity I also checked some older kernel images:

3.11.10-03111010-generic, which is the last 3.11 iteration, is working fine:
$ acpi_listen -t 10
ibm/hotkey HKEY 00000080 00007000

and its broken with 3.12.0-031200rc1-generic, which is the first 3.12 release candiate.

I hope this helps to track it down.
