psmouse.c resync failed

[Andy Baumhauer]

Kernel 2.6.24.3-22 and 2.6.24.3-12 lockup my Dell D830 laptop with a 
Synaptics touchpad.  If I leave the keyboard for a brief period of time, 
and return, the mouse pointer will not move.  A few seconds later (and 
the system monitor shows high CPU utilization), the mouse will stutter 
to life, and the /var/log/messages shows:

After a few times going through this process, the caps lock and scroll 
lock will start flashing on the laptop.  The system becomes unresponsive 
and you cannot even ping the host.  The only thing that works is a hard 
power cycle.  I have tried booting with nohz=off and noapci, to no 
avail.  This is making Fedora totally unworkable.

I have added information to Bugzilla # 427697 which looks like the 
problem I am having.  Unfortunately, it is marked with LOW priority.  
There have been numerous other posts on other distributions about 
psmouse.c and stuttering mouse behavior.

Here is the xorg.conf:
