Thanks a lot for the patch! I've applied it with some minor adjustments.
I'll sync it over to the external svn later tonight.

Adding a bi-directional version of the PDMICHAR interface would be an
option (if it makes sense), and/or having the parallel port device fall
back on the PDMICHAR interface if it cannot find something better.
The ioctl wrapper is fine for development, but for I would prefer that a
final implementation uses a parallel port specific driver/device
interface instead of it.
