    Intel released the 8254x Developer Manual in late July, so some
    information is now available. You can download a PDF from
    SourceForge:

    http://www.sourceforge.net/projects/e1000/

    Unfortunately that document doesn't appear to have any chip errata in it,
    so you may have to search the Linux driver for the work-arounds it's using,
    but it's better than having no documentation at all.
