I asked for a wiki account, but haven't got one yet *hint hint* :)

Well, It was quite straightforward with buildroot, just that the last
steps (mkelfImage, compressing the kernel image with lzma and using
coreboot) needed to be made manually. Then I decided to use buildroot
with its default settings since the 2.6.22 kernel is good enough for
now, and the fact that is more integrated makes it much more suitable
for a development system, and I can't afford to waste time on the,
collateral task of making buildroot work.

The buildroot was re-configured for my needs, I configured the kernel to
contain KVM support and some other collateral things, then did the same
with busybox, and I added a make test target that runs qemu with my bios

Afterwards, I included a buildrom make target for my kvm tools, and
started to hack on them and make them compile and link against stuff
that will be present in the bios image. 

These tools also needed some stuff like zlib, which I had to include in
buildrom and now I'm having some issues with uClibc, which is missing
some features present in glibc that are needed by the kvm tools
(specifically aio support, by now), and I must add them to uClibc.

That's my current status.
