Is this an effort to boot an ACPI-mode kernel,
and then kexec a non-ACPI kernel?

Doing so could confuse the heck out of the platform firmware,
which will think that an ACPI-mode kernel is still running.

Note that it is a historic artifact, now considered a bug,
that ACPI uses the MPS code.  We should be divorcing these
two bodies of code rather than mixing them further.
