I think it's time for us to get smart. We should probably bite the bullet,
figure out how to turn IDE on in linuxbios, then do dram init, then by the
time we hit the kernel ... the IDE is up.
We can't escape memory init. I still don't want to bzero it, though; I
want to copy it to itself, at least the first 8 meg or so. Or I want to
figure out that we just reset and ECC is ok. How do we tell power-on from
reset?
