hard icon touches and suspend improvements

These have been in my tree for a while (for months actually), and work
fine for me.

1) hard icon touch support, from hpcsh (mostly c/p'ed) but also with
   support for raw kbd (for X).

2) run MI suspend code when pressing the suspend button, most important
   thing are the powerhooks, so pcmcia cards supporting those hooks will
   be powered off (tested with ne(4) and an(4)).

Unless anyone has an objection, I'll commit them.
