So I went through the changes from 2.6.27-rc5 until the SHA1
ID ec0c15afb41fd9ad45b53468b60db50170e22346 and there were
definitely no E1000 or E1000E changes during that time.

Included in there is the HPET revert and other similarly themed
changes.

commit b4609472116bb806a95e98d04767189406c74c70
Author: Linus Torvalds <torvalds@...ux-foundation.org>
Date:   Fri Aug 29 14:38:03 2008 -0700

    Revert "x86: fix HPET regression in 2.6.26 versus 2.6.25, check hpet against BAR, v3"
    
    This reverts commit a2bd7274b47124d2fc4dfdb8c0591f545ba749dd.

Some power management related changes stand out slightly:

commit 9d3593574702ae1899e23a1535da1ac71f928042
Author: John Kacur <jkacur@...il.com>
Date:   Tue Sep 2 14:36:13 2008 -0700

    pm_qos_requirement might sleep

and

commit 74c4633da7994eddcfcd2762a448c6889cc2b5bd
Author: Rafael J. Wysocki <rjw@...k.pl>
Date:   Tue Sep 2 14:36:11 2008 -0700

    rtc-cmos: wake again from S5

The rest of the changes in that range look completely benign.
