Make absolutely sure you are editing the correct config file.  
Most problems I have helped diagnose related to settings being 
ignored in a config file, end up being that the options were put 
into the wrong config file.

XF86Config-4 if found by XFree86 4.x, will be used.  If you've 
got XF86Config-4, and XF86Config, and edit the latter, the server 
will never read the config file and never see the changes.

This is quite a common problem report, so I thought I would 
clarify this, even if it is not the actual cause of your problem.
To see the config file search path order, consult the XF86Config 
manpage.

Hope this helps.
