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

using Phillip R. Shaffner's advice.

However,  rpm -i kernel-2.6.9-42.EL.src.rpm
yielded no driver source anywhere under /usr/src ; in particular, no 
arcnet source.

So, I tried Seth Bardash's advice to use up2date:

  up2date --get-source kernel

This yielded a number of fetches, but terminated with

    An HTTP error occurred:
    URL: 
http://mirror.centos.org/centos/4/updates/i386//SRPMS/kernel-2.6.9-42.0.3.EL.src.rpm
    Status Code: 404
    Error Message: Not Found

No driver source present afterwards, either, anywhere under /usr/src.

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?

Thank you,
