I think there does not exist a perfect solution right now. It is possible to get most parts of Dolphin running (including the Ajax requests with some minor modifications), but there do still exist some graphical problems. It seems that the problem is not only caused by Dolphin but also by the used gd-library. Actually I was only able to try it with Mac OS 10.4 and I am not sure if the newer versions (10.5) are providing better support for this functionality.
