2.5.73 Mouse

[John Weber]

My mouse suddenly stopped working with 2.5.73.  I am using a Synaptics 
Touchpad --
with comes with a Dell laptop.  (I will test with an external mouse later).

The SERIO I8042 driver seems to find my mouse, interrupts are firing, 
and I enabled
the old /dev/psaux so that userland doesn't see anything different. 
Most importantly,
the same config worked with 2.5.72.  I noticed that dmesg was slightly 
different across
the two versions which suggests that something did change.
