Hmmm I didn't think that elf_load() should be being called by the 
openBSD IEEE-1275 bootblock at all (it looks like the source just opens 
the file as a standard device) - is it?

Assuming this was the case, I was going to suggest removing lines 
495-528 from elf_load.c and then seeing what a CONFIG_DEBUG_OFMEM build 
returns - at a minimum it should show which regions are being specified 
by the boot loader, and which are being automatically allocated.
