Given the above, and that it starts behaving once gnome-power-manager is turned off, it's starting to sound like a bug in gnome-power-manager. I'm adding a task for that package.
Given that your hotkeys work but the rest of the keyboard doesn't, and that lshal output hasn't changed, it sort of sounds like something is stealing your keyboard device. Presumably X is able to reclaim it from doing a vtswitch. Not sure what would cause that.
