one of the issues we see with joysticks is that they have no clear mapping
to X's notion of pointers and keyboards. buttons on a joystick cannot easily
be mapped to other buttons since the mapping is not obvious. likewise, axes
are more likely to interfer than be useful. Sascha did a talk about the
joystick driver which I summarised here and it addresses these issues

third button emulation was added in Feb 2011.

friction costing was added to synaptics in July 2010 and it is, for better
or worse, enabled by default in the driver.
