I confirm the problem with "safe graphics mode".
I have an NVidia GF 6600 AGP graphics card, which does not work with "nv" driver. It works well with proprietary "nvidia" driver and "vesa".
When booting 6.10 beta there is no difference to me between standard boot and "Start Kubuntu in safe graphics mode" - both the ways result in corrupted display (vertical lines). This "safe graphics mode" worked well in 6.06.
