And following on to that, libpayload based payloads are now multiboot
enabled, so you can load them from GRUB in the BIOS environment of your
choice. I've tried coreinfo on both traditional and coreboot with no
problems. So you can use the above trick to test libpayload payloads
without flashing too. The next step is teaching filo how to load
multiboot payloads, and of course, convincing the desktop distributions
to ship coreinfo.. :)
Thanks to Robert for all his help.
