The ALPS pad would be working now, but that kills of the
Trackpointer currently:

http://bugzilla.kernel.org/show_bug.cgi?id=8864

When my problem is solved and both UltraNAV devices fully
working that bug report will be closed. So you can track that
one.

If you only want to use the ALPS pad then you can add this to
alps.c:

{ { 0x73, 0x00, 0x0a },	0xf8, 0xf8, 0 }, /* ThinkPad R61 8918-5QG */

However i prefer the Trackpointer and want to use the ALPS pad
only for wheel scrolling emulation etc. so this can't be the
final solution.
