Same to me with Acer5930g, NVIDIA9600GT, NVIDIA drivers from nvidia web page, because jockey cannot install nvidia-current drivers correctly. After wake up from suspend to RAM, the kubuntu says that there is no usable conf. in xorg.conf and I have to reinstall the drivers. Same option box as when you update kernel and forgot reinstall NVIDIA driver.
