Hi,

This patchset is a test-drive for a new USB input driver for eBeam
devices.
Currently, only the Luidia eBeam classic projection model is supported
(usb id known).

Patch 1 and 2 are here to let the ebeam driver be choose to handle
the device instead of the generic-usb hid one (totally useless).

Patch 3 is the actual driver.
Some things to consider :
- I'm not familiar with kernel coding (i've based my work on
  usbtouchscreen.c) so the code certainly contain flaws.
- There's 2 64/64-bits divisions needed, don't know how to handle that the
  right way to be efficient and portable.
- There's 14 custom sysfs files. Yes.

Beside this, the driver run fine with 3.3.6 and 3.5.0 kernels on x86_64.

Thanks for your help.
