Unpublished PhD work and unresponsive advisor
Unless he is truly a co-author and collaborator, beyond supervision, then you can publish it on your own. Advising doesn't automatically imply co-authorship in most fields. If he must be a co-author for ethical reasons, then prepare the paper with him as co-author and send a copy along to him stating that you intend to submit it to "xyzzy" unless you hear any objections. Of course this gives the advisor a sort of veto, but a co-author would have that in any case. 

Within the paper, thank him for his help, as well, I think. Thank him when you send the paper to him as well, of course.
