It's not likely that files were simply renamed for no reason. So I'm
thinking yes, there is a difference. And this is exactly the kind of
difference we were looking for. So let's dig a little deeper.
So try this: Boot each kernel and each time save the output of lsmod
(e.g.: "lsmod > lsmod.kernel.1") and make separate copies of the file,
/etc/X11/xorg.conf and then then look for differences in those two pairs
of files.
