I'll see if I can post a patch to make v1 build.
Back when I last tried this, it looked to me as if RAM init worked (or
at least I thought it worked), but I'm not so sure anymore. I didn't
actually boot a kernel, I only got some debug messages over serial
which I interpreted as 'RAM works', but that might have been wrong...

Don't even try VGA, that's unimportant at this stage and it'll surely
not work anyway.
The goal right now is to get RAM initialized so it can be used at all.
We want to be able to copy stuff (say 0x99) to RAM, then read it back
and it should still be 0x99 (for example).
That's not working at the moment.
