Sounds good!

If all things would be obvious, we would have noticed the device
permission problem a year ago :-)

Previously nvidia's conftest.sh script would not run at all with Debian
packaged kernel headers, but maybe this has changed now. At least I saw
something like enumerating all the tests when building 358.xx modules.
So maybe we can stop maintaining out own conftest.h in the 355+ future.
But also here it would be important to delegate compiler and options
selection to kbuild. Checkin for header existence should be via
compiling stuff, not test -f (the kernel source layout must be opaque).
