CVS Module installation > update mollom module > Site Broken *** How to revert changes to that module using CVS??

Well, installing and updating modules is much easier using CVS, and I discovered lots of how to's for doing just that... The problem is I can't find any on how to revert the changes to a module I upgraded via CVS...
So, if I ran the command
cvs update -dP -r DRUPAL-6--1-1.10
How do I revert that back to the old version?
is reverting basically the same as something like so:
cvs update -dP -r DRUPAL-6--1-1.09??
Thanks
