Comment 3 for bug 576648

This is caused by a failure to detect the kernel version by the 'conftest.sh' script, which attempts to compile an incomplete kernel module.

There are a variety of issues causing the failure. I've current addressed the one that affects builds for 2.6.39 and later (compiler should use optimisations else static variables are compiled out), and a related problem where the nv-linux.h preprocessor directives won't recognise v3.x kernels (tests only for < 2.7.0).

I have working patches for both nvidia-173 and nvidia-current right now, and have updated the packages locally. I'll upload debdiffs once I've been able to test the built modules.
