My understanding is that the backslash makes the scoping explicit.  It puts
it in the "root".  So as long as _PR was not inside another scope, \_PR and
_PR should be equivalent.  Similarly, \_PR.CPU0 is the same as CPU0 defined
in \_PR.

The scoping seems to make a difference in the size of the generated AML
code, but besides that shouldn't matter too much.

Thanks,
Myles
