I have been successful in building an nvidia.ko that works with my xen kernel
(2.6.24-16-xen on hardy). I've achieved that through awful hacks, basically I
applied (partly by hand) the patch found at
http://www.nvnews.net/vbulletin/showthread.php?t=78632, and I basically bypass
the conftest.sh script (I changed it to force the use of Makefile.kbuild and
generated the conftest.h with the headers of the -generic kernel).
Now, I'm trying to understand *why* the conftest.sh script fails so miserably,
both for the makefile test and for a few of the compilation tests. It turns out
that when it tries to compile a simple test file (attached) that tries to get
the kernel version, it fails with the following output:

Which makes me think that, either something is broken in the -xen
headers, or the test program should add another #include (why then is it
working with the -generic headers?) or there is some macro that should
be defined with -D and isn't; but, well, I'm a bit lost here. Hope this
helps.
