Hi, I have a Dell Inspiron 510m with intel extreme 2 graphics card working to suspend to memory.
Suspend to memory normally only works when you use the vesa driver in X.org with a small resolution (1024x768 or so). What I do is starting a second X session with this driver and then suspend to memory. After resume the X session will be stopped and you will be back in you original X (or original console, just were you started the suspending).
Further I use the 855resolution program to use the 1400x1050 resolution and the ondemand scaling driver (always, not only on battery) for cpu frequency scaling.

If I forgot something, please ask. Hopefully it will work for you too. If someone can tweak this, or can suspend to memory on a different way, I'd be very glad to hearing that. Tnx in advance.
