You have to patch your kernel (see attached patch against 2.6.24-rc3 +
0.18-20071112) to disable thinkpad-acpi keypresses reporting.

And you will have to manually catch the keypresses. Here, hal is
consused because there are two 'laptop_panel' and gnome-power-manager
can't adjust the backlight correctly.
