actually yeah i've seen this... in a bizarre failure situation in a system
which physically had RAM in the boot node but it was never enumerated for
the kernel (other nodes had RAM which was enumerated).
so technically there was boot node RAM but the kernel never saw it.

"Node 1" is the boot CPU, though, right?

From the looks of it I would say he probably has the boot node numbered 1.
The e820 map is also "interesting" - doesn't list the first 256 bytes,
which corresponds to the first quarter(!) of the real-mode exception table.
