The usermod command changes the parameters of the user root.  Have you tried
to give root the UID 600?  To change a file to permissions 600 the command
is chmod.  That said, I don't know enough to get you out of it.  I would
try one of the GUI user managers, but in turn, you would need to run it as
root.  I would have thought that root is root, and its uid doesn't matter. 
Plainly, that is not correct. Man usermod says that the change will be
applied only to files in root's home directory, and others must be changed
manually - don't ask me how.  Perhaps the simplest answer would be to run
usermod again and change root back to what it was (0 (zero) in my Mandrake
system.)  Do it in the same place that you ran it before.

HTH,

Doug.
