Thank you for advice. I have installed Kubuntu 9.10 recently released. Hotkeys
(Brightness and sound) are working from a box. Questions are:
What package is responsible for Panasonic hotkeys? I cannot find
panasonic-laptop.
What about another hotkeys (video out switch, hibernate, harddisk)?

@Andy
I just rebooted with your kernel (2.6.27-11lb222324apw2). The kernel just
works, no problem. But I see no support for the hotkeys. No pcc-acpi module, no
response to any hotkey pressed, and

Am I missing something?

I have had a look at the module and it appears to be pretty small and

It seems that support for pcc_acpi has been dropped since kernel 2.6.23
due to acpi changes.
A patch version of pcc_acpi needs to be built from latest sources and
