FYI:

Part of the reason for the HACK status for
debug.minidump=0 is that for old PowerMac's,
while the loader handles the relocatable
format, it does not actually relocate
the kernel: The result of the kernel load
still matches the debug information.

Stored virtual vs. dumped physical addresses
when the values are distinct would be an issue
on various powerpc's for memory references
where it matters.

The code depends on such loading and only
handles physical==virtual contexts for
debug.minidump=0 .
