I was not able to install new kernel, because after installing ubuntu from flash drive to hard disk it was not able to boot. The problem was how I created flash drive. I made it like a CD, using dd command. When I created it with usb-creator-gtk touchpad is working. So, this bug is only if booting iso file. Flash disk created by usb-creator-gtk is working and touchpad is recognised. Sorry for false report.
