After a few (hundred) trials with Suse, i switched over to RH9. My X needs about 2 Minutes to come up now. But then it runs without any problems incl.3D.
I just read another thread with an advice I'll try tonight:
Here is what I did to my XF86Config file:
Option "IgnoreDisplayDevices" "DFP, TV"
VendorName "Videocard vendor"
BoardName "NVIDIA GeForce 3 (generic)"

The bold line seems to stop the graphics-card from searching for TV or LCD's
Sounds if it's worth a try....
