When I first installed Oneiric, both touchpad and trackpoint worked fine
(almost): both pointing devices were listed in "Pointing devices" application,
settings like scrolling emulation for trackpoint and two-finger scrolling for
touchpad worked too.
The only problem was "lost synchronization" message in log which were
accompanied by temporary (1-3 secs) freeze of pointer from time to time
(approximately one time per 10 minutes). Both pointing devices successfully
survived suspend-to-ram.
Recent update has changed all.

# Now both trackpoint and touchpad doesn't work right after boot in half of
cases.
# Even if they work after boot, they often stop working after approximately an
hour of uptime.
# Even if they work after an hour of uptime, they loose scrolling function and
start detecting as mouse, not touchpad/trackpoint.
# Additionally instead of random freezes trackpoint now goes crazy and starts
jumping on screen and clicking everywhere for two seconds.
# Both trackpoint and touchpad don't survive suspend-to-ram.
# Sometimes when trackpoint works after boot it behaves very strange: pushing
stick to the left causes pointer to move to the left but then immediately move
back half of runned way.
Pointing devices are almost completely unusable now!
What I've tried:
# Load older kernel - doesn't work.
# sudo modprobe -r psmouse && sudo modprobe psmouse - doesn't work
# Turn off "disable touchpad on typing" - doesn't work
