Those messages and the problem of the combo card reader and firewire
not working after s2ram has been present for long
(https://bugzilla.kernel.org/show_bug.cgi?id=35452
dmesg here: https://lkml.org/lkml/2011/5/15/55).

Before 3.4-rc1 there was nothing wrong with the touchpad (and keyboard
and reboot) after s2ram, and the problems are somehow separate.
Rafael's patch fixes the new problem, any suggestions for the old
one would be warmly appreciated.
