Yes, this restores the previous behavior, i.e. the buttons work again.

One other thing I would like to change though, setting
hw.psm.synaptics.touchpad_off=1 disables the touchpad/clickpad as expected, but
it also turns on the buttons.
This was also the case pre-r306355.
I almost exclusively use the trackpoint, so I would like to be able to turn the
touchpad off, but keep the buttons working.

Never had this problem before. I have been using this hardware for months,
tracking HEAD. It seems to work now, with the patch applied and no debug on.
I'll keep running it with this patch and see what happens.
