Public bug reported:

In Ubuntu 10.04, the touchscreen & stylus of my Thinkpad X201 Tablet
used to work reasonably well (there were issues with rotation, similar
to #726142). After upgrading to 11.10, the touchscreen is not longer
functional. The kernel recognizes the device apparently:

Touchscreen as /devices/pnp0/00:0b/tty/ttyS4/serio2/input/input8

but X detects "input/output errors":
