[Bug 659712] [NEW] New device name enumerated after suspend/resume cycle

[Vaibhav]

Public bug reported:

On Thinkpad T61, the touchpad and trackpoint are enumerated using the
i8042 driver to be serio devices. In 2.6.32 series kernel from Lucid,
the trackpoint was always enumerated as serio2 after a resume and its
sysfs entry remained under /sys/devices/platform/i8042/serio1/serio2/.

With Maverick 2.6.35 kernel, after a resume a new device entry is
created and older lost. So from serio1/serio2, it changes to
serio1/serio3 after a resume, then to serio1/serio4 and so on. I set
parameters using sysfs.conf for trackpoint sensitivity/speed and those
are lost since a new device entry is created.
