The gianfar simply stalled. I found a patch from Anton Vorontsov [1], which solves exactly the same problems for SMP, and it fixes it for RT_PREEMPT also. So if anyone has trouble with gianfar with RT_PREEMPT, you should definitely give it a try. It has been accepted by David Miller, so it should end up in Linus tree at some point, but I would suggest applying it to the 2.6.33 RT_PREEMPT tree also.
