** Description changed:

  I have an ETPS/2 Elantech touchpad in my Asus Eeepc and since installing
  oneiric, 3 finger taps always registers as whatever TapButton1 is set to
  in synclient. The touchpad would appear to use the version 2 protocol,
  since it has 6 bytes per packet.
  
  I reported this issue against linux instead of xserver-xorg-input-
  synaptics because booting into the natty kernel (2.6.38-11) in oneiric
  fixes the issue and 3 finger taps work correctly.
  
  As further testing, I built a kernel from linus's git (so it doesn't
  have the elantech version 3 patches included with the latest oneiric
  kernels), and 3 finger tap still didn't work, so my guess it is a
  problem with one of the changes to include the new kernel multi-touch
  code. I don't know if this means there is a bug in this new code, or
  some issue with xserver-xorg-input-synaptics and the new code.
  
  I reverted the multi-touch changes in drivers/input/mouse/elantech.{c,h}
  (back to the version in 2.6.38, still need to figure out exactly where
  the changes were introduced), rebuilt just the psmouse module and 3
  finger tap works correctly again, so if it is a kernel problem, it would
  appear to be localized to just that module.
  
  I will continue to investigate, any assistance is appreciated.
