Possibly your problem's root is not having noaccel option enabled. A search 
this list's archive might turn up something helpful.

I have this software and hardware on openSUSE:

0a:03.0 VGA compatible controller: XGI Technology Inc. (eXtreme Graphics 
Innovation) Z7/Z9 (XG20 core)


xorg-x11-server-7.6_1.15.99.902.2-2.1.x86_64 (aka 1.16.RC2)

Linux g5eas 3.14.0-2-desktop #1 SMP PREEMPT Fri Apr 11 09:18:16 UTC 2014 
(e0d4304) x86_64 x86_64 x86_64 GNU/Linux

working with this xorg.conf file:

Maybe it can work as a framework for you to create a usable xorg.conf 
matching your display. Most likely you will not need DisplaySize, which is 
there to force a specific DPI. Most don't need to disable DPMS as I do 
either. All lines starting with # can be omitted. If you get it to work, try 
again with NoAccel line commented out, then report back here your results 
with and without.

When attaching logs, please append .txt to each so picky web browsers will 
open them instead of wanting to save to disk first before they will open them 
as the plain text files that they are.
