Third party modules which have been integrated into Debian can
still be built, without the linux-image installed, by
a) cd /usr/src/kernel-headers-foo, call make-kpkg
b) KSRC=/usr/src/kernel-headers-foo, call make-kpkg
All the other third party modules I have seen look for
/lib/modules/$(uname -r)/build; which implies that the kernel image
is installed, since it is running, and thus the postint.d scripts
would already have been called.
So, we are talking about modules that do not work with
kernel-package, which have not been integrated into debian, and yet
need to build against a version of the image package not installed. I
know of two such modules, nvidia, and vmware, and at least
vmware-config.pl asks where to find the headers, and people can
provide that.
