I've not looked at it, but I've thought about it.
Since our plan is still to skip 3.4 and tackle things in earnest for 4.0, I'm planning to wait to do driver work. Of course, I'll probably want to look into this earlier than 4.0 if possible (I'll be gone most of September, though). There's another driver bug I want to look into, as well (my recover-from-hosed-backend code doesn't work with AOLserver3 though it worked fine in AOLserver2).
