Yes, though a bus layer isn't actually a necessary prerequisite.

As I mentioned in the recent "Smarter compilation for target devices" 
thread[1], having individual devices do byteswapping is bogus. A while ago I 
reworked the TLB handling, so there should now be spare bits that can be used 
for things like byteswapping.
