The results of an IRC conversation, notably a missing include path:

<tseliot> BenC: I'm using Nvidia's makefile as usual. Nvidia's
conftest.sh tries to build the test file with cc -D__KERNEL__
-DKBUILD_BASENAME="#conftest12386" -DKBUILD_MODNAME="#conftest12386"
-nostdinc -isystem /usr/lib/gcc/i486-linux-gnu/4.3.2/include
-I/lib/modules/2.6.28-1-ub-generic/build/include/asm/mach-default
-I/lib/modules/2.6.28-1-ub-generic/build/include -o conftest12386
conftest12386.c
<BenC> tseliot: looks like an nvidia bug
 tseliot: it's missing -I/.../arch/x86/include
<BenC> tseliot: note, fglrx built fine with latest header packages...I
didn't test nvidia
