Just last week I sent in a bunch of patches that make device resets work correctly in all circumstances. They haven't been accepted yet, and when they are it might not be in time for 2.6.8. But eventually they should get into the kernel. If you're interested in trying them out in the meantime, I can tell you what BK respository to start with and what patches to apply. If you want to stick with the standard kernels, then I don't think 2.6.7 is much more advanced than 2.6.6.
