Bug Description
Binary package hint: linux-source
Same kernel, except compiled with thinkpad_acpi as module or compiled-in. Hardware keys work fine, though.
Brightness applet and gnome-power-manager brightness options do not work when thinkpad_acpi is compiled as a module.
However, all works fine when thinkpad_acpi is compiled into the kernel.
This is on a Thinkpad T40p
Kernel version: 2.6.22-14
Suspend2 patches applied, but patches don't affect thinkpad_acpi files.
Generic kernel's brightness doesn't work properly either, but I have not compiled the generic kernel with thinkpad_acpi built-in. I would assume it's the same.
