This is interesting... you apparently have a ACPI 3-style e820 BIOS as
evidenced by the [1] markers, but Grub presents it as legacy style.
Now, the kernel shouldn't care, but this at least gives a clue.
Something that might be worthwhile is to add printf's to the kernel's
e820-parsing routine (in arch/x86/boot/e820.c) and figure out why it
doesn't like the output. It's a bit strange that meminfo would produce
sensible-looking output (well, legal, at least; presenting a two-byte
range is rather beyond crazy, and so forth) and the kernel wouldn't
accept it, as the code is intentionally very similar.
