@DevenPhillips: I'm a fellow bug sufferer, rather than Ubuntu maintainer, but if you're experiencing the same bug as myself then I've found I reliable workaround.
Setting the `i8042.kbdreset=1` parameter to the kernel on boot seems to result in consistent detection of the touchpad. The easiest way to do that for me was to edit the /etc/default/grub file with the following line: GRUB_CMDLINE_LINUX_DEFAULT="i8042.kbdreset=1" and then running `sudo update-grub`. For me, this workaround was free of side-effects. In my situation the touchpad would either be detected (and work fine), or not be detected *at all*. I don't recall it being detected as the wrong device. As such, I've no idea if my workaround would be effective in your situation.
