+ I'm using Ubuntu 12.10 amd64. Kernel version 3.5.0-18-generic
+ 
  On my previous notebook, the touchpad was controlled via psmouse driver.
  
  There are many reports about drivers not working for touchpad.
  This touchpad seem's to be completely broken...
  
  Lenovo's Driver Site has the following Windows-drivers for download:
  Touchpad Driver (Synaptics, ElanTECH) 16.2.10.3/11.4.3.3
  TouchPad Driver (Cypress, Synaptics, ElanTech) 2.3.7.25/15.3.39.0/10.4.2.8
  
  I've tried the following methods to trigger hardware detection, without
  success 8-(
  
  - modprobe psmouse proto=imps
  
  - kernel parameters: i8042.noloop=1 (and also i8042.debug i8042.reset
  i8042.nomux i8042.nopnp i8042.noloop)
  
  - tpconfig -i (but this command also on a PC without PS2 Port shows the same 
message)
  Found Synaptics Touchpad.
  Firmware: 8.96 (multiple-byte mode).
  Sensor type: unknown (0).
  Geometry: rectangular/landscape/up.
  Packets: absolute, 80 packets per second.
  Corner taps disabled;         no tap gestures.
  Edge motion: none.
  Z threshold: 6 of 7.
  2 button mode; corner tap is right button click.
  
  - cat /sys/bus/serio/devices/serio1/modalias -> serio:ty01pr00id00ex00
  
  - different drivers: psmouse-alps-dst-0.4, psmouse-alps-dst-1.1
  
  - Fn + F6 (Toggle on/off): There's only this message via dmesg:
  "[17041.473447] ideapad_laptop: Unknown event: 5"
