No AC adapter ACPI events on Sony Vaio VPCS12X9E

Hello,

As the subject line summarizes, I do not get any ACPI events when I unplug/plug
the AC adapter on a Sony Vaio VPCS12X9E.

The laptop is currently running an up-to-date installation of Kubuntu 11.04,
but with a manually compiled vanilla 3.0.3 kernel. For the record, the same
problem also exists with the stock version 2.6.38 kernel that comes with
Kubuntu 11.04.

I have also reported this bug at
https://bugzilla.kernel.org/show_bug.cgi?id=41762

Since I am going to travel soon and lose physical access to this hardware,
I wanted to ask if there is anything I could do to debug this problem.
I have included the acpidump and ACPI debug outputs in the bug report.

Any help would be appreciated.

Regards,
