With this patch, the trackpoint works again. However, I can't set any
options like sensitivity or speed. Perhaps there is already something
going wrong during the build. Modinfo only shows this:

whereas it showed many more options with the old
trackpoint-2.6.11-rc3.patch-1:

However, your new patch creates some files in
/sys/devices/platform/i8042/serio0:

a13x:/sys/devices/platform/i8042/serio0# tree
.

    |-- sensitivity
    |-- skipback
    |-- speed
    |-- thresh
    |-- transparent
    |-- upthresh
    `-- ztime

9 directories, 37 files

But echoing values in some of these files like sensitivity or speed
doesn't do anything. Finally, regardless of which patch I use, dmesg
always shows this:

Synaptics Touchpad, model: 1, fw: 5.9, id: 0x2c6ab1, caps: 0x884793/0x0
