I dusted off my ATI all-in-wonder remote and was trying to get it to
work with VLC (so far unsuccessfully; I'm still untangling the
multiple mapping layers between hardware scancode and X event), and
I had a look at the ati_remote.c driver.

I started hacking on it.  Mostly I thought the ati_remote_tbl[]
array was wastefully large.  It gets a lot simpler when you
realize that, in the 4-byte report, data[1] is actually a checksum
and not part of the keycode.  data[1] = data[2] + data[3] + 0xE5.

Having looked over the input layer documentation, I have decided that
the ati_remote driver could use some love.  I'd like to convert it to
use the generic scancode to keycode mapping and autorepeat logic.

IMO, ati_remote.c and ati_remote2.c should be adapted to use the ir-core
(soon to be rc-core) interfaces. I've got remote2 hardware myself, so
doing the conversion for that driver is already on my personal TODO list,
but its a long queue of more important things ahead of it first...
