The intention is not to use a BIOS from AMI for instance.
Then I think you are looking for CoreBoot. That does not currently support that particular atom (it does support some of the older z5xx models with the us15w chipset.)
Coreboot is what used to be called linuxbios. You could then use openfirmware on top of that as the interface.
I could be wrong, perhaps openfirmware is enough (apparently on the OLPC that is in fact the case).
