F8: Suspend/resume on Dell 9400 laptop

[dpet]

	I have not been able to get the suspend/ resume to work. The
cycle seems to work except that the backlight does not light. I have
tried "quirks" and combinations of them without effect (obviously not
every combination!). It used to work until "several kernels ago", but I
didn't record when it stopped.
	The video card is Nvidia 7900, using the Livna driver, and
currently kernel 2.6.24.3-12.fc8.
Thanks
