Yes. But not only the x86 emulation itself is interesting, but also the
legacy bios emulation around it. There are so many branches and forks
out there, we _have_ to do something to unite them, otherwise we cannot
reach our goal in this area. Nobody knows what the others are really
doing.

I am going to set up an GNU Arch repository on openbios.org asap so we
can set a starting point for development.

We need some clarification on what parts belong in this repository, and
which ones don't. Like, where do the PCI access functions go, logically,
in this picture?
