ok -- downgrade to xserver-xorg-input-synaptics 1.5.99.902-1 (debian package) built with -O0 -- no crashes within a week -- so I guess it is indeed synaptics to blame. If I find a chance I will "upgrade" to 1.6.0 and see if crash comes back... I would hate to do such silly bisection but I guess it would be better than doing nothing and simply waiting ;-)
