It fixes an endianess problem with kms and the in tree x86-video-ati
among other things.
It has been tested on various i386/amd64/sparc64/macppc machines
on a range of hardware from r100->northern islands.
Because of ati.c revision 1.5, it will not be selected by
autoconfiguration code, so people who want to run this version of the
driver on their radeon cards need an explicit "Device" section in
xorg.conf.
