Again that one? Grrr.

pretty right to think that your iasl is broken somehow.

In order to get rid off the _PPC things, I checked that the _PPC thing
was in a SSDT via something like this:

../pmtools/acpidmp/acpixtract SSDT < acpidmp.out > ssdt

Then:
iasl -d ssdt
in order to decompile it to ASL.

So you should not worry about those \_PR.CPU0._PPC (for example) by
defining an external one (see diff below).

Lastly, for the Z007 horror, replace them with Zero or Ones (or any
other integer values).

But I'm wondering what iasl are you using?  It seems totally broken
to me.
