Bug Description

I am using breezy daily 050930 on a Compaq Presario R3000z AMD64 system. The
touchpad stops working after resuming.

The kernel says "i8042: failed to resume active multiplexor, mouse won't work."

Reloading the psmouse modules fixes it.

A better fix

This patch puts the unload/reload of psmouse above the chvt into X this allows
the synaptics driver in X to properly initialize the touchpad. Without this the
mouse is very slow after resuming.

There is probably a better way to implement this, but I do not know the ACPI
scripts that well, so I leave that to you.
