Thank you so much for your suggestions. i am using KDE as my default 
desktop environment and gnome is also installed in my centos box. when i 
login using KDE or Gnome, each time i issued the command 
gnome-mouse-properties. it effectively make the touchpad work.

secondly, i already told that when i switched back to the old kernel, my 
touchpad works as intended. no problem at all.

lastly, yeah i got the idea to install a fresh vm and then try to update 
the system one by one in the manner you suggested. After then i can be 
able to let you know what happened with those updates.

Thank you very much
