Actually, I think that the sync was the problem, but eieio might be, too.
I note similar assmbly junk for both, so... who knows....

Yeah.  I'm planning on releasing certain development kernels (possibly not
mainstream) that use plain old sync and eieio and see what speed
difference it makes.  We might find out that MkLinux's drivers aren't so
bad after all....  You never know.  Anyway, I don't think that register
has always been supported, but somebody with more memory of the MkLinux
coding history could say more (maybe).
