These patches actually made situation kind-of "worse" for this
particular issue.
I've tried patches with post 2.6.32-rc4 kernel and after second
suspend-resume cycle I got typical "order:5" failure. However, this
time when I manually tried to bring interface up ("ifup eth0") it
failed for 4 consecutive times with "Can't allocate memory". Before
applying these patches this never occured -- kernel sometimes failed
to allocate memory during resume, but it *never* failed afterwards.
I'll go now for another round of bisecting... and hopefully this time
I'll be able to trigger this problem on different/faster computer with
e100-based card.

Driver has been fixed? The one patch that I saw (by davem[1]) didn't
fix this issue. As of 2.6.32-rc5 I see no fixes to e100.c in
mainline, has there been another than this[1] fix posted somewhere?
