If you plan to run Wine, you
will need to tell fglrx to not corrupt the fs register.
To do this, add the line:
to the "Device" section in ''/etc/X11/xorg.conf''. This supposedly causes about a 10% hit in opengl benchmark scores, but at least things don't crash. See also http://wiki.winehq.org/fglrx and http://www2.ati.com/drivers/firegl/readme0325.txt
