Ok, the quirks required for consistently-working suspend using the xorg
nv driver (the open-source-ish driver, not the nvidia proprietary
driver) are s3_bios and vbemode_restore. Using the proprietary driver
(for those searching for answers in the future, I know you won't support
it in hal-info), the quirks required are s3_mode and save_pci.

Here is the output you requested:

You can see in there that I have the quirks that work for the nv driver
enabled. I'm not running gnome any more on my ubuntu machine (xmonad
instead) but tested the quirks by running 

  /usr/bin/ suspend

as root.

I have not yet tested hibernate, but will be doing so very soon.
