according to image David's machine fails the same way for numa=noacpi (unfortunately).
Actually I found one bug in memory_present -- in case of SLAB code being activated (which should be later stage of booting so it's not our case now) sparse_index_init could fail with -ENOMEM and we'll try to deref NULL in further. I'm fixing it now but again -- it's not the issue we have now.
To Jiri: good catch! :-)
