Nah, no automatic updates. I think somehow I have to tell it to update that tag, but I'm not quite sure how. I finally found something from google about it here:

[Linux] Journal SVN Id Tags

It states that updating of the $id$ tag isn't automatic with SVN, as it must be with CVS and that I need to turn it on.

AHAH. I figured it out. I have to go in and set the svn:keywords property to every file in the repository (ooooh, fun), and then it doesn't modify it on commit, only on update. 4 commits later on one file to figure that out haha, hope nobody looks at the revision history of that one.
