Preserving memory...

Hey, I'm working to get some in-memory crash dump kernel patches, and I've
run into some problems.  I've got a couple of questions that I hope someone
can answer for me:

First, is there a way to tell powerpc hardware (Macs in particular -- for
now) to preserve memory across a system restart?  It looks like it does this
by default, partially.

Secondly, if I can get the first part to work reliably, does anyone know
what regions of memory should be avoided, i.e. are thrashed by OF etc?
