"In the file /boot/grub/menu.lst you need to add i8042.nomux to the end of the kernel line:
kernel /boot/vmlinuz-2.6.28-11-generic root=UUID=8fd4r505-1372-4s39-8r3fd3-a4fr56ygdf6063 ro quiet splash i8042.nomux
Now just save and close the file, and reboot the netbook. When it comes back, your touchpad should work."
