Brian- Is your tree non-ultrametric because it contains extinct taxa from the fossil record, or is it simply an undated tree of extant taxa?
To my knowledge, there isn't yet a satisfactory solution to the first (no BISSE for paleo-phylogenies) but if the second then, it seems the best route would be to date it and use the methods developed for ultrametric trees.
