No synaptics touchpad on pbook-12"

["Antonio-M. Corbi Bellot" <antonio.corbi@ua.es>]

Hi list:

I've been using appletouch with my pbook12" touchpad and with driver
synaptics for a long time. I used it with my own compiled kernels from
kernel.org.

Since I decided to give a try to the official kernels in etch (now I'm
using 2.6.18.dfsg.1-11 + xserver-xorg 1:7.1.0-12) I have noticed that I
do not have support for the synaptics extensions.

Xserver-xorg boot time messages (relevant part only) are:

(II) LoadModule: "synaptics"
(II) Loading /usr/lib/xorg/modules/input/synaptics_drv.so
(II) Module synaptics: vendor="The XFree86 Project"

My synapctics conf is this one:

      Option        "SHMConfig"             "on"
EndSection

My problem is that this configuration worked with my own compiled kernels
but not now with the official one.

I've checked that evdev and psmouse are loaded, but still no
/dev/input/event* devices appear: 
$ ls -l /dev/input/

Any idea about what can be happening?
