    You could boot into single-user mode and do some command line work. Hold command-S at startup to get to a shell prompt, then try something like:
    mount -uw /
    chmod -R 755 /
    If that gets it to boot, you'd better run Disk Utility and run a permissions repair ASAP.

    Now that I think about it the easiest, safest solution would be to boot from your OS X install CD and open Disk Utility and run the permissions repair that way.
