Just for entertainment value; with this applied, 8.5 will successfully get all the way to beyond quiesce(). I didn't think about whether this actually makes any sense at all (presumably not), beware.

Ha cool - this is based on MOL's device tree, right? :) There is actually some RTAS code in OpenBIOS but it is disabled by default - check out config/examples/ppc_config.xml and CONFIG_RTAS. I've no idea if it was ever finished or is any good though.
Note that as this is a CONFIG option in order to test you'll need to blow away your build tree, i.e.
rm -rf obj-ppc/ ... (enable CONFIG_RTAS in ppc_config.xml) ... ./config/scripts/switch-arch ppc make
ATB,
