Unfortunately that died, because Oracle stopped being willing to cooperate with the port [1]. Of course, I understand why they might not see it as being in their commercial interests to support porting their OS to a competitor's hardware; but, I think their turn away from openness with Solaris accelerated its decline rather than delaying it.

(Disclaimer: ex-Oracle employee, but I was never working on Solaris directly, just on higher-level middleware stuff which sometimes ran on Solaris, and I really don't know anything about this topic beyond what has been reported in the media.)
