I'm kind of wondering where this will break, but I don't remember why
the RESET_BAT was put in exactly - the point of making sure the BIOS
doesn't get confused by the advanced modes is correct, and is required
at least when a keyboard is set to "Set 3", but RESET_BAT is a too heavy
hammer anyway - we could just make sure to switch the kbd/mouse to
'default' modes instead of doing a full reset.
