I think you are correct they are separate issues.  I posted both methods
so we could decide in which direction we wanted to go with the ptrace
interface.  I would like to see the single word at a time interface that
currectly exists be patched to support AltiVec so we can get debugger
support working.  I would like this done to the 2.4.x tree.
