We're trying to avoid the bounce buffer mess, which is really complex,
by running elfboot out of the boot block. This code includes a really
dumb allocator in elfboot which may or may not work. It basically
allocates off the elfboot() stack.
This builds, but elfboot is not tested. That's next.

accordance to the newboot document:
* reset vector (16 bytes)
* vpd (240bytes)
* boot block (8k - 256b)
* lar archive (256-8 k)
The boot block is kind of simple, still. It enables pmode, car, and
starts looking for an initram module in the lar archive.
Note: This doesnt do much at the moment,
as gas seems to produce buggy code in init.S.
Take this as a suggestion of how it might work and please provide
patches fixing it and bringing it into shape.
