Hello,
xorg seems to not work for me anymore, having upgraded from 8.1 to 9.2 
and using the same xorg configuration that previously worked. The 
following is xorg log file. Unfortunately, I do not have a log file saved 
from when it was working. I'm not really sure what's going on here, but 
the warning message "Can't map IO space!" seems suspect. In searching for 
that string in the xsrc, it led to here:
