Thanks Ken,
i tried to got a clue of problem in Xorg.0.log file in both kernels. but 
i was unable to get it. The thing i notice is that in old kernel Xorg 
log file is

(II) config/hal: Adding input device ImPS/2 Synaptics TouchPad
(II) XINPUT: Adding extended input device "ImPS/2 Synaptics TouchPad" 
(type: MOUSE)

Where in the new kernel Xorg file contains

(II) config/hal: Adding input device SynPS/2 Synaptics TouchPad
(II) XINPUT: Adding extended input device "SynPS/2 Synaptics TouchPad" 
(type: TOUCHPAD)

so does it make a difference?
