Yep, you're right. We should do it that way. I was thinking of offering
a way to let a precompiled cpio image become the initramfs of the built
kernel, but it is really better to let br2 handle it all.

There are, however, two problems with the existing code.

1) the linux modules are installed unconditionally which we must avoid
   our case
2) the initramfs target is currently broken

So, forget about this patch, I'll provide two new ones to make this
work.

Thanks,
Daniel
