Actually, it's pm-utils, because I'm using fedora.
This, by the way was years ago, beginning with FC6. In FC7 we got the driver to the state where vbestate save/restore worked for it and added it to the hal database. Today, at FC9, I've just been busy filing a bug with fedora because the i915 drm now seems to do everything and actively screws up if vbestate save/restore is used (so all the work I did with FC7/8 now needs to be undone).
