I still think we shouldn't reward shit hardware by complicating up our DMA mappings internals. :-) If you're going to do it anyways, we use a nearly identical allocation bitmap algorithm under sparc64 so maybe you can take a stab at trying to put your code there too. I'm more than happy to test and integrate.
