That means shmget failed. The kenel config you provided does show SYSVIPC enabled, however... You should run the "nv" driver that came with XFree86 to ensure that you can get the server started with working MIT-SHM support (ie. a benchmark like "x11perf -shmput500" succeeds). Not only do NVIDIA's drivers require SHM support, it is performance critical for other drivers as well. Mark.
