Morphos With a delay of a few days, Genesi has released the schematics to its Pegasos Rev.2b5 motherboard.

This shouldn't be a relevant problem.

Internal firmware of Pegasos motherboard is SMART FIRMWARE, a firmware inspired by OPEN FIRMWARE, and it follows same guidelines.

So it there should be no difficulty to port BSD version of Open Firmware to Open Pegasos layout (since the moment it will be completely made open to public).

Think of it as a kernel with device drivers. It provides a simplified view of hardware, so the bootloader/OS doesn't need to know all the specifics. The firmware, however, does. It's not a monolithic silver bullet.

So, has the firmware been released, complete with board-specific routines for CPU/cache/memory/chipset initialization, disk/network/IO drivers, etc?

The only open OF implementation that I know of is the one released by IBM, for their JS20 blades. (64bit unlike the Pegasos; work needed) It needs those board-specifics implemented, AFAIK.

I'd be surprised if Genesi could open-source Smart Firmware, as it's not their code, AFAIK, but property of CodeGen. They could probably open their Pegasos-specific Forth/C/asm code, for use with the SLOF, but have/will they?
