Nod, I shall have to have a check through the ones here if I can.

Since I don't understand the input layer well enough yet, can you
confirm if it is possible to add new mappings in without changing the
source? I.E. if laptop <foo> has another hotkey not yet considered, is
it just an FDI for hal, or is it a source change in the kernel?

It was more: will events come out of both the notify method *and*
the /proc/acpi/toshiba/keys stuff, or will they only come out of the
notify method if it can be enabled? (I'm just trying to establish that
things polling /proc/acpi/toshiba/keys won't end up causing duplicated
events).

Assuming I'm just being over-paranoid or not understanding the minutae,
then I give this a +1 because the behaviour is certainly desirable since
it'll allow the tosh laptops to not wake up regularly to check for
hotkeys.
