Since you talk about grabbing the remote repository, I assume you're cloning it. In that case, you should probably simply clone up to the revision you want:
$ hg clone http://server/repo -r revision_you_want
That will simply clone all revisions up to the specified revision and hg incoming
will then show you the later revisions.
If you don't know the revision you want before you've cloned the repository, then you can use hg strip
to delete the extra revisions.
