I played a bit with uinput the last days. It is not a big problem to
create a virtual keyboard in user space and send key events to the
kernel input layer. All depending programs will recognize this events
including X11.

I thinks this is the way to go for special laptop buttons not supported
by kernel driver. There is no need for a second key event distribution
system like dbus and last but not least HALd don't have to cope with
keys at all.

I don't know yet where this piece is placed in the big picture but as
interim solution it would be easy to change IAL to use uinput instead
of dbus.

  Best Regards
