This stuff by the way is the result of 5 hours of grepping through git
logs and all 2.4.x and 2.6.x kernel patch files to locate when each
change nvidia cares about happend, which really is something nvidia
should be doing instead of their stupid conftest.sh script.

Do you have any contacts at nvidia that might be interested in taking
over this file to make the nvidia driver fully kbuild compatible?

The only thing it doesn't cover is the CONFIG_XEN detection stuff as
far as I can tell.  I couldn't make sense of what their test was trying
to do for that.
