Thanks that solved the problem, no more lockups.

auto-dev doesn't work for me and I don't have time to check it
out. While poking around I did find another problem though.

There is also a kernel problem, to summarize, the touchpad is
identifying itself differently then with previous kernels and thus
isn't recognized at all by the kernel.

I don't know how much effect it actually has since some initialization
is also done through X.

The main problem I found:

Under 2.6.9-rc2-mm4 in alps.c under function alps_get_model, for the
call to ps2_command with PSMOUSE_CMD_GETINFO (the E6 report output) the
output is 00 00 14 instead of 00 00 64 like it was before and what is
expected, so the touchpad isn't recognized at all as an alps. (I can't
figure out whats causing the difference or how the return value is
received at all, and I don't have any more time to dig further into it).

Second problem is that hardware tapping is disabled by default
(I found no way to enable it externally) which in my case causes most
taps to be interpreted as double clicks instead of single clicks.

After fixing both things and X to use the right device things finally
work again.
