The 2.6.27-rc7 changelog shows this problem has been fixed for e1000:
http://www.kernel.org/pub/linux/kernel/v2.6/testing/ChangeLog-2.6.27-rc7

and this patch in the -mm series fixes it for e1000e:
http://marc.info/?l=linux-mm-commits&m=122038324200305&w=2

Clearly, we need to ensure the second patch makes it into 2.6.27
final; the corruption is reported to occur during suspend/resume
cycles.

Thanks,
  Daniel
