Input devices not usable on boot or logout/login

[Ben Howard]

After upgrading from 11.04 -> 11.10 Alpha2, the integrated laptop keyboard and mouse are disabled and not usable. I was able to use input devices after plugging in external USB devices. However, after logging out and then back in, the external USB keyboard/mouse was unusable until it was unplugged and pluged back in.
