Dmitry,
I turned on i8042.debug and it produced a lot of noise, and I couldint
make out what it was trying to tell me. So I put some debug prints in
synaptic.c and psmouse-base.c. In the case where both touchpad and
trackpoint are enabled in the BIOS I get the following failure in
psmouse_probe(). I have attached the psmouse-base.c and synaptic.c for
you reference as to where the prints are coming from. Dont know why
psmouse_probe() PSMOUSE_CMD_GETID would fail on the pass-through device.

When both are enabled in BIOS what protocol does the kernel use to talk

Yes it uses Synaptics TouchPad.
if (max_proto> PSMOUSE_PS2&& synaptics_detect(p .. etc...
I should say here that the trackpoint is not detected. And sometimes
(very random) the trackpad is detected as PS/2 Mouse when touchpad
and trackpoint are enabled in the BIOS... here is what it looks like
in dmesg when it shows up as PS/2 Mouse instead of TPPS/2 IBM
TrackPoint.

Ah, so we do know that the touchpad has a pass-through port.
I guess you can try booting with i8042.debug with touchpad enabled and
disabled and see where exactly we fail to enable trackpoint the the
former case.
