Feisty Beta almost works - it manages to wake up from suspend2ram just fine, only the display stays off, as others have noted. It can be fixed, though (at least it works for my nx7400 flavor).

There were 2 steps to enable display to resume:
1) I compiled i8042 as module, configured /etc/default/acpi-support to unload psmouse & i8042 before suspend.

2) It's also necessary to set "SAVE_VIDEO_PCI_STATE=true" in /etc/default/acpi-support.

Now, there is only one problem left - DPMS sometimes does not work, that is, display backlight stays on even when the display is supposedly turned off by gnome power utilities (screensaver, etc). I have yet to figure out how to solve this last problem.
