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.
