Possibly proof of concept is the wrong term.
What Pink does works. I can't throw J. Random kernel at beoboot and have
that work. I can't throw memtest86 at it and have that work. I can't use an
SMP aware kernel with beoboot. And last I looked beoboot had a bulky user
space that makes it hard to squeeze into flash as well. So beoboot
with 2 kernel monte works for a certain interesting subset of cases
but it does not handle the general case.
Except possibly for the exotic driver case 512KB is a large enough
FLASH chip to put in both LinuxBIOS and a kernel. You have to work at
it with a 512KB flash chip but it is doable today.
