I'm glad you did, as Aron's mail is doing that funky "turns up already
marked as read" thing, so I missed his reply.
After applying the above diff, it complained about unset symbols.
CONFIG_MEMORY_HOTPLUG
CONFIG_ACPI_HOTPLUG_MEMORY
which I set.
Then it complained about
CONFIG_VIRTUAL_MEM_MAP
which the above diff removes. I added it back.
The resulting config looks sane to me, but you may want
to double check things are ok in builds 2456 and above.
