X multihead issue: mouse gets trapped on right screen

[David Hagood]

Given a multi-headed X server in Zaphod mode (i.g. having 2 logical
screens :0.0 and :0,1), the mouse is getting stuck on the right most
screen.

This is a known (and fixed!) bug in Xorg:

However, it does NOT seem to have made it to Fedora, as my FC10 machine
is showing the very symptom.
