passing KSRC=/lib/modules/KVERS/build (as done by m-a) does not work for
the "split" header packages shipped in Debian. There is
/lib/modules/KVERS/source, too, and it is *different* from .../build .
So we would have to pass SYSSRC and SYSOUT to the NVIDIA build system -
or just KERNEL_UNAME (and let the build system figure out the correct
paths).
Of course that broke your case (unified, but not installed, kernel
source) I've tried something in branches/304 that seems to work ...

That KVERS alone is not working seems to be specific to the NVIDIA
kernel module - and their assumptions about kernel source layout in
their conftest.sh script (instead of leaving such details totally to
Kbuild). But I'm much happier now that we can use conftest.sh directly
and we no longer have to maintain our custom conftest.h that substituted
conftest.sh

What's likely not going to get working is the dkms build with
non-installed kernel headers (i.e. not available via
/lib/modules/KVERS/{build,source})
