Let it be known that today I was actually able to get my Linux laptop, using the proprietary NVIDIA drivers no less, to suspend to RAM. I'll give you a moment to pick yourself up off the floor.
Using a less-than-stock build of OpenSUSE 11.0, KDE 4.1.3, the latest NVIDIA drivers and a Dell Precision M6300 I was able to successfully both SUSPEND TO and RESUME FROM RAM. I crap you not. I even took a picture.
Wow. That's... like... historic.
