Uhmm...  You got that wrong.  Here is the recommended pattern:

Basically, *always* call Dispose(false) from the finalizer, if present, but avoid having a finalizer unless you need one.

Fortunately, it looks like SslStream has no finalizer, so I guess the GC will never call any variant of SslStream.Dispose.  So I guess it's no problem.

Finalization seems to be correct.  But Dispose hangs.  Doesn't seem to be the fault of SslStream, but one of the dispose methods that gets called, either directly or indirectly, from the SslStream Dispose method.
