Mouse scroll issue after kernel build

view story

http://askubuntu.com – I have a Intel Cedar trail netbook. For graphics to work, i had to build kernel 3.1 with the drivers. I followed the steps in this document - http://download.intel.com/support/motherboards/desktop/sb/enabling_hardw... After doing that, now my graphics is fine, but my mouse scroll does not work. Is that because I have not build the kernel properly? Have i missed selecting some options in the kernel compile menu? It will be nice if someone can help me. Also my wacom bamboo tablet is not recognized, i have installed the xserver-xorg-input-wacom drivers. Much (HowTos)
