I guess this can be interesting for the openmoko as well...

I think the interesting points are the use of readahead, to compile a
monolitic kernel (a very small initrd) and to setup the video mode in
the kernel (that if I understand correctly would save X to re-initialize
the hw...)

hope this helps.
