If "fully working" for you means you want gparted then I think I'll have to disappoint you. I don't even know where to begin debugging. But I intend to release a basic Wheezy/armhf image in the near future (pretty similar to my old Wheezy/armel image - but hopefully with fewer stupid bugs) that others can use to create more "end-user-friendly" images. It always bothered me that I didn't actually understand the inner workings of qole-based images (all we have so far) and since I'd have to start over from scratch for an armhf transition anyway I thought this might be a good opportunity to dig deeper.
