[ltp] Fedora 11, resume unreliable on X40

[Christos Papadopoulos]

I think we now have success.

In case anyone is still reading, yet another followup to my own
comment.  Disabling hi-res timers by adding highres=off to grub.conf
seems to fix the problem. I have gone through several successful
suspend/resume cycles, certainly more than any other time before the
change. (Thinkpad X40 with Intel graphics card)

Christos.
