Unless you need a lot of CPU power and have the experience and background
in laying out highspeed multilayer boards you might want to look at embedded
powerpc or arm designs.

Sure just write your own boot code to replace the bios

It only needs the BIOS for boot up and for PCI. You can backport the direct
PCI from 2.1.x if you need it. You will need to write a PCI configuration
module to replace the PCI bios config.
