I was able to get the original 4.4 kernel from http://mirror.centos.org/centos/4.4/os/SRPMS/kernel-2.6.9-42.EL.src.rpm

However, rpm -i kernel-2.6.9-42.EL.src.rpm yielded no driver source anywhere under /usr/src ; in particular, no arcnet source.
Looks like you have never-ever before worked with src.rpms. Head on to /usr/src/redhat/SPECS. There should be one single .spec file. You will have to run (assuming you're using i686 kernel):
# rpmbuild -bp --target=i68 <this_spec_file>
and then CAREFULLY re-read mail from Seth Bardash, and follow the instruction he provided.
Note: An exploded source tree is not required to build kernel modules against the currently in-use kernel.
That's basically what I want to do -- just build the arcnet code and insmod it.
So, what am I doing wrong? How do I get that source?
If you want to build arcnet module without rebuilding the whole kernel - you will have to somehow get this module for 2.6.9 kernel in a separate distribution with a separate Makefile, install kernel-devel RPM package for your current kernel and build it against it's headers. It's always possible to extract module source code from original vanilla kernel sources, but that requires a lot of experience with building and rebuilding linux kernels, so I wouldn't suggest you to give it a try.
