YES!!! It finaly woks!!
Using the 97series Beta Driver I finaly was able to suspend while in X!
I even have full AGP Support through agpgart..
So I guess it was not Kernel Developers fault or Xorg-Devs
But in the end: I'm happy
Even suspend-to-mem work.. for some seconds.. then System freezes.. but this can be anything, doesn't have to do anything with nvidia.. next Target
