Cool!
I wonder if this could also be of use to other arch's...

Maybe at some later stage mkisofs / mkhybrid could be adapted to
support this directly? In a way similar to the El Torito boot file
image...

It was accepted by Alan Cox for 2.0.37-pre5, so I think it's acceptable :-)

Doesn't the VGA/TGA display slow down to the speed of the serial port if
serial console support is enabled? That would not be nice; it would help
if that can be disabled by some boot parameter (or maybe enabled instead?).
I can build a kernel with serial support and see how that works on my
