Thanks Bryce!

The MT work in X has taken a different form from what was proposed in
the message linked in comment #31. However, we are getting near to
having an XI 2.1 protocol extension for MT set. I hope to introduce some
of the MT work into Natty soon.

Kernel drivers need to be written for the MT evdev protocol to work
properly. Either the slotted or non-slotted protocol will work, though
slotted is better. If the kernel presents working MT evdev data, it will
work with the X MT solution. It sounds like the NextWindow proprietary
driver does not handle MT data quite yet though. The proprietary nature
of the driver will have no affect on its ability to function in the MT
stack in ubuntu.

Proprietary MT drivers will always be a second class citizen on Ubuntu
because they are not installed by default. In fact, this is the first
time I've ever heard of a proprietary MT driver being used in Ubuntu. I
would strongly recommend NextWindow to open the code or even just the
specifications of the hardware so users have the best experience
possible.

In short: Yes, the proprietary driver will work when it is updated for
MT support. Nothing extra will be needed in evdev or elsewhere.
