There is no special consideration for user space. Since all useful memeory is
mapped 1-1, guess user space would work as is. Unless iam missing something
here.. so yes.. there is no protection with 1-1, but guess its like
compatibility mode until the code gets converted over.
Keith: cced says some of the user space side also is getting converted over with
some driver support possibly. So this is an interim problem until X catches up
with it.
