I have just gotten a PR8 aged site to link to mine, they created a page for me so officially my page and my link is PR N/A but with Google now concentrating on the trust issue, this is great for me. And just so you know, my site is maybe 2 months old, has an "under construction" homepage and yet I still got the link. And in all honesty it really wasn't hard, just try a few things and when one sticks, throw everything at it.
