On my system (Dell Inspiron 8200) the problem was solved by forcing the use of the nvidia built in AGP driver, this is done by the Option "NvAGP" "1" setting in your xorg.conf as well as blacklisting the related non nvidia agp driver in modprobe.d/blacklist (mine is intel_agp), gone many days without any lockups now.
