I can confirm that 1.6.2-1ubuntu1~precise2 doesn't completely fix the bug on Lenovo T420s.
While I have not seen any random crashes for some time, the touchpad can still be killed by the test described in #81. After some cycles of disabling it by hotkey with fingers on and reenabling with fingers off the pad is not working anymore. However, this procedure doesn't crash X so far, as it reliably does with ..~precise1 before.
