Thanks for the reply.

touchpad working in kernel
2.6.32-71.el6.x86_64

problem in the following kernel after running full system update
2.6.32-358.14.1.el6.x86_64

because i am a novice centos user, kindly let me know how can i confirm 
which driver is being used (which command to issue at command prompt)?
