Comment 32 for bug 222324

Confirming that panasonic_laptop module in Jaunty fails to support brightness keys, since it does not create the /proc/acpi/pcc/* interfaces which the panasonic brightness scripts in acpi-support expect.

I've been using the pcc_acpi module with the suse patches (http://software.opensuse.org/search?baseproject=openSUSE%3AFactory&p=1&q=pcc-acpi) module up until 2.6.28, when a compile error showed up due to this (http://kerneltrap.org/mailarchive/linux-kernel/2008/9/11/3261284) kernel acpi change. This was simple to patch, and the module works.

Patch attached, meant to be applied after all patches in http://download.opensuse.org/repositories/openSUSE:/Factory/snapshot/src/pcc-acpi-0.9-4.15.src.rpm
