 Dear Sir/Madam,
 I am reproducing this problem on an HP 8710p with 8.0-RELEASE.  The notebook has a Synaptic pad+stick combo.  I find it interesting that this hardware was working on 7.2 without any problems, but now in 8.0 there is this pain: the mouse freezes up for a few seconds, particularly when switching between consoles and X.
 As per Artur's original description, I have increased the log level and confirm that I have exactly the same problem... with some interesting additions.  Seems that button 9 (right mouse button) on the touch pad also generates button 4 events.  This is happening at the moused layer and this then gets passed up (so things like xev report 4 and 9 Button Release events while the button is held down).
 Regards, Mike Grant.
