Problem with touchpad

Patch can be applied to current revision of port tree.
Here are changes
I recompiled xorg-server and mouse drivers and noticed that nothing is
attached to touchpad. xorg now looking for synaptics driver. Is it
expected? We have support for synaptics in kernel and recently it was
unproved to support 2 fingers touch.
I installed synaptics driver. Without hint, it failed to attach with
error that it can't detect protocol. This is common one, if you need
exact error, I can repeat test.
So, I put
Section "InputClass"
Identifier "Mouse"
MatchDevicePath "/dev/psm0"
Option "Protocol" "psm"
EndSection
psm is protocol driver can't detect. I think, in FreeBSD this is the
only option. Maybe hardcode it into driver?
As with kernel's touchpad driver, synaptics driver worked until reboot
and I must say, this driver is even worse - mouse is not moving at all
and just emits random key presses. Xorg log is a little bit more
interesting. It's big, so I posting it as gist.

1. kbd tried to attach to USB mouse. I suppose it failed due to rights
issue. /dev/ukbd0 is root:wheel, while I'm only operator. Should I test
what will happen if it actually attaches? But I don't think this is the
right thing to attach.
2. Every touch of synaptic driver emits synaptics touchpad found block
in xorg log.
3. (EE) Synaptics driver lost sync... got gigantic packet! is when I
actively use touchpad. So, I doubt this is the root of the problem.
Delicate touching :P keeps this error from spawning.
