So that's all that is needed on the userspace side?  Or is there a
driver for X that also goes along with this patch that is available
somewhere?

Can I also get a TODO file for this directory that lists what needs to
be done to move it out of the staging tree, as well as an email to
contact for patches and questions?

What's with the formatting changes to this file?
