Ok, your ALPS touchpad is identified as:

{ { 0x22, 0x02, 0x14 }, 0x00, { ALPS_PROTO_V2, 0xff, 0xff, ALPS_PASS | =
ALPS_DUALPOINT } },	/* Dell Latitude D600 */

You mentioned that commit 92bac83d introduced your problem:

    Input: alps - non interleaved V2 dualpoint has separate stick butto=
n bits

Hans, can you look at this problem as it is clearly problem with
protocol V2?
