mount /dev/wherever / -o remount -o rw

That command remounts the root partition read-write, so you can edit stuff. As 
Maria mentioned, rescue disks are also useful here.

Incidentally, the reverse command (with "-o ro" rather than "-o rw") is useful 
if you're about to do something that might screw your machine up something 
terrible - a nice case of mechanical amnesia covers a multitude of sins :)
