Yes, we have to avoid this hardcoding and make it useable for
everyone. As you saw kevin is now starting to make a generic keyboard
driver, and as far as we can we have to go in that direction, it will
save us a lot of time later when new devices arrives.
Also a cr2 ( he' is the guy who has done most of the port to htc
universal) are trying to make it clean as it could be.

Yes that sounds like a good idea, lets try to keep it up to date.

Yes this is a quite tricky work i've heard, someone told me that the
h4000 had the cleanest code for it (i saw that you had made it) . We
are having problem with this on the 2.6.16 kernel for the HTC
Universal.

Yes you probably right, but we also have a irc channel at
irc.freenode.net #htc-linux
There are allways activity there in the evenings (CET).
