Hmmm, you're right, the ram_limit limit shouldn't be applied if
CONFIG_HIGHMEM is defined.  Your patch looks a bit wrong though, we
need phys_mem.regions[0].size to reflect the total amount of ram we
are going to be using (including high memory).  I haven't had a chance
to test the highmem stuff on a machine that has a lot of memory myself

Well, we would need to know where the machine check happened,
preferably with a stack trace.
