I can also confirm this bug on a Dell Vostro 1510 after upgrading from Ubuntu 8.10 (Intrepid). Adding "i8042.reset" to the bootparameters of kernel 2.6.28-11-generic in the /boot/grub/menu.lst solves this problem for me too.
Another interesting thing: When booting the old Ubuntu 8.10 Kernel 2.6.27-11-generic WITHOUT adding the "i8042.reset"-option, keyboard and touchpad are working fine as well.
From where I'm standing, this problem seems to be related somehow to a strange phenomena only occouring when booting kernel 2.6.28 with mkinitramfs. (Because of combusters observations seen in this comment: https://bugs.launchpad.net/ubuntu/+bug/344698/comments/17)
