You're proposing a new interface between bootloader and kernel as a
temporary hack just to work around that until we fix it properly?

That seems like overkill to me. I'd just go for is_geode() as you
suggested, and maybe PCI configuration tricks to detect the lack of VSA
so we can be _fairly_ sure it's OLPC before we poke at it?

Or why not try '!page_is_ram(0xffffffc0 >> PAGE_SHIFT)' if it's just to
avoid that particular warning? :)
