From kernel documentation: The first kernel driver to utilize the MT protocol is the bcm5974 driver, where examples can be found.

Here is a blog from the Xorg input system maintainer on his thoughts regarding multitouch: http://who-t.blogspot.com/2010/10/thoughts-on-linux-multitouch.html

In any case, this is a work-in-progress. The issues to resolve are myriad and difficult, to say the least. However, there is some support for MT capabilities in the current Linux kernel, but which devices are supported are limited. My suggestion is to contact the device/pad manufacturer to determine what MT chip set they are using, and then looking to see if it is in the currently supported device list.
