Interesting.  This maps physical button #4 to buttton  #11.  I will
take a look again, but in my psm device, I never saw button 4 events,
just button #1 and button #3 under generic psm mode. Mouse taps always
showed up as button #1 so it was impossible to differentiate between
tap #1 and real #1. (unless something like moused was mapping #4 to
#1, hmm something to investigate)

Were you running psm/generic or psm/Extended Synaptics or using ums0 ?
Does your ums0 mouse show up as Broadcom 4503 ?

running moused -df -p /dev/ums0 -t auto gives no mouse events to
movement/buttons at all.
