This happens with xorg-server > 1.7.1-1,
Xinerama and
a screen which has Position set with LeftOf or absolute but not in order e.g.

Screen 0 "Screen0" 0 0
Screen 1 "Screen1" LeftOf "Screen0"

or

Screen 0 "Screen0" 1200 0
Screen 1 "Screen1" 0 0

Moving the mouse to screen1 will make the cursor jump around and after a while X crashes.
Downgrading to this X server helps:

X.Org X Server 1.6.3.901 (1.6.4 RC 1)
Release Date: 2009-8-25

# uname -a

I don't think this nvidia/platform or distribution specific, since this only happens with Xinerama enabled. On disabling Xinerama the screen offset like above work.
