Where did you get this size from?

INMEM_CON_LEN in skiboot is 0x100000

Even if booting a kdump kernel, you're going to have a device tree with
the appropriate nodes present to *programatically* find out where the
console is. You should certainly do that.

We've never said that the skiboot memory map is ABI, so it *may* change.
