This commit provides the necessary changes and new files for Opie to

have partial support for the Palm LD, TX and Z72 handheld computers.

This commit is based on a patch submitted by Cristiano to the opie-devel
list. The patch itself comprises work done by Alex Osborne, Cristiano,
Sergey Lapin, Jan Herman and Aaron. Thanks goes to them for sticking with
the patch and expanding the number of devices Opie works on.
