The buttons are set via an /etc/X11/xorg.conf.d/50-synaptics.conf file, 
which looks like this:

Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"

Most of it is probably not needed, for I have an Alps, not a Synaptics 
touchpad. I'm using Xorg server ver. 1.9.2 with synaptics driver 1.3.0. 
During startup, I'm getting something like this in my Xorg log file:

and it is OK. During suspend/hibernation touchpad is removed from the system 
and is reconfigured after resuming. But then something strange happens, for 
in the log file I can see something like this:

Almost everything is exactly the same as during startup, but finally I have 
an error, that the hardware is not recognized. And tapping is not working 
(although the rest is working fine and I can turn tapping back on using 
synclient).
