I've asked the core team about this exact problem a while ago, and have been 
told that there is no mechanism for differentiating between a resource 
change caused by modification in the workspace and a resource change caused 
by a resource being sync'd with the file system. I've opened a bug report:

http://dev.eclipse.org/bugs/show_bug.cgi?id=14211

Luckily in the CVS plugin we only really care about changes to the 
provider state (changed revision...) and this information is stored
in files that we control and are team-private (e.g. CVS/*). By saving 
the timestamp when ever the plugin changes the CVS state of files in 
the change listener we can tell if the plugin changes them or a 3rd party.

I hope this helps.
