Not sure if this is still relevant, but I've got a ramdisk configuration
which booted OpenBSD 2.4 on a 4MB machine. I have managed to get more
memory since, so I haven't carried the changes over to 2.5 (but it
probably wouldn't be such a big problem)... If anyone needs it I can
probably make it available..
