Comment(by tvoverbeek):

 Here todays logs collected into 080816.tar.bz2.
 These were done after going back to Q2E12 firmware. With Q2E13 the mouse
 was mot usable in 703.
 There are 3 runs on build 708 and three runs on joyride-2302.
 Each run was done while exercising Bounce (3Dpong).
 Before each run the power was reset (power off, battery removed and
 reinserted).
 The logs ending in .0.log are taken without setting
 sys/modules/psmouse/parameters/tpdebug to 1.
 The *.1.log files have tpdebug set to 1.
 The touchpad behavior was normal under 703.
 The touchpad seems to behave better with tpdebug set to 1 under
 joyride-2203.
 There are again a number of recalibrations in the 2302-x.0.log files
 So it smells like some marginal timing issue somewhere.
 I'll try to do an other set of runs tomorrow.
