Not to be picky but... I followed the link to IBM's site.
"The Open Desktop Workstation is based upon the Genesi Pegasos, a CHRP based motherboard. Integrating selected Open Firmware and running multiple (15+) operating systems"
15+ operating systems? Are they counting individual linux distros?
"Running several distributions of Linux out of the box along with OpenBSD"
Huh? I though OpenBSD got cancelled on Pagasos?
I really have nothing against the Pegasos, I just think they need to check their facts.
