Yep, I can see the keypresses being registered all the time:

------------

KEY: LCD backlight down
LCD stepping -1 -> 4
DBus lcdBacklight: 4 5
DBus process watch
KBD: inhibit clear 0x08 -> 0x00

KEY: LCD backlight up
LCD stepping +1 -> 5
DBus lcdBacklight: 5 4
DBus process watch
KBD: inhibit clear 0x08 -> 0x00

----------

The cause is definitely the Nvidia drivers - the setting gets 
(physically) applied only when I switch to a text-only screen, 
regardless of whether I've run pommed from the text-only screen or 
gnome-terminal

I'll see if I can play around a bit with the smc driver. For now I just 
launch and stop pommed whenever I need it.
