The rvm does have two uses beyond switching quickly between two versions of ruby: It makes it trivial to upgrade your ruby when a new version comes out, and it takes some of the configuration problems out of linux, so it should make it easier to straighten out whatever happened.
One other thing I am freshly and painfully aware of (since I haven't set up rvm yet myself) is that when you go back to an older project, and discover that Rails will no longer run at all because there's some newer Gem in you path and your configuration files aren't specific about versions, you kinda wish you had a gemset in the project, and could step into the Wayback Machine and just get that little client change made without endless refactoring and tail-chasing.
