It's not. There's /proc/bus/input/devices for that.

Please don't use numeric keys. The Linux keytable is already almost
depleted, there's not much space left (according to Dmitry Torokhov),
hence they're now registering new keys only very seldomley. Using numeric
ids won't be future-proof. Textual strings are quite a bit more future-proof.

keyfuzz uses textual strings. If you really think you shuld go ahead
with doing this stuff from HAL you might want to copy that part from
keyfuzz since it uses gperf to generate a perfect hash function for
looking up those keys using GNU gperf in O(1):

Is it? As I read http://www.gnome.org/mobile/ it's only "under
consideration". 

But anway.
