Finally, it looks like the problem has gone. At the least, durng the past hour the touchpad works fine.
What I have done is:
1) removed all unnecessary xorg-input drivers and kept the only following:
xf86-input-mouse, xserver-xorg-input-evdev, xserver-xorg-input-vmmous, xserver-xorg-input-synaptic
2) maybe it was non mandatory, but removed all unnecessary xorg-video drivers and kept the only needed by my vcard and abstract:
xf86-video-v4l, xf86-video-vesa, xf86-video-fbdev, xf86-video-vmware, xf86-video-intel
3) removed all nvidia and radeon tools - maybe not mandatory
4) booted in recovery mode and regenerated Xorg.conf.
Now I work with the touchpad more then an hour without any troubles.
Tried to reboot, etc.
