I have no clue why DEBUG helped, but it seems to have been simply dumb
luck as the issue came up again with DEBUG still on.  An easy workaround
was to compile psmouse as a module and unload/load it during the suspend
cycle (automatic with the hibernate script, it has psmouse in it's
blacklist).  I haven't dug into it to see what exactly doesn't get
initilized during resume that should.
