Awesome thanks.

Actually, for this use case I have somewhat different idea in mind.
Please refer to the 'Safety Net' section in the options editor spec:


Basically the idea is that we would manage a set of xorg.conf's for the
user, and build in the ability to select between them at several
different levels of the O/S - grub, bulletproof-x mode, recovery mode,
and when booted into the desktop proper.  As well, I'm tying in an idea
from dustin kirkland whereby a configuration can be associated with a
given hardware configuration, and the xorg.conf swapped in or out at
boot time based on the hardware layout.  Obviously, getting that to work
right will be tricky, but it solves a range of different use cases
in addition to wacom configuration.
