ok.. even though there wasn't anything useful in the Xorg logfile,
after recompiling the kernel i get:
hw.nvidia.agp.status.status: enabled
hw.nvidia.agp.status.driver: nvidia
hw.nvidia.agp.status.rate: 4x
hw.nvidia.agp.status.fw: disabled
hw.nvidia.agp.status.sba: disabled
Now this almost doubles the frame rates, which is nice to see :)
Alas, the problem still remains :(
Will try upgrading everything tomorrow..
