I think it's called xmodule=nv. BTW it was just an example, you probably don't need vsync=60.
You could start with: knoppix failsafe just to see if it'll boot. Then start experimenting with the right cheatcodes for your computer. Could be that you need framebuffering which would then be: fb1280x1024 or fb1024x768 or fb800x600, or try vga=normal.
