The sample you provided create figures with the same relative size of text
and title on Windows and R 2.10.1. I remember, however, that I had similar
problem before, so possibly it has been fixed and you are using an older
version or a different operating system.

Also have a look at the Cairo devices; I have used them with good success in
similar cases.
