Miscelaneous Debian Questions: PowerMac

[De Served <deserved@cogeco.ca>]

I have a couple of miscelaneous Mac related questions. 

First Question: 

Is it possible to netboot an old world PowerMac? I have a beige G3 that
is waiting for a Debian install. I want to experiment with running this
machine diskless. This, obviously, means netbooting the machine. Is it
possible? 

I have spent several hours on Google looking for the answer to this
question. The Debian installation documentation says that yaboot is
required for a netboot, and that yaboot only works with new world Macs.
So the official Debian documentation says nay to netbooting old world
powermacs. 

Further Google searches reveal that at least a couple of people have
reported successfully netbooting an old world powermac, but there was no
mention of how they did it. At least, there was no mention that I could
find. There also appear to be a number of people who have had problems
getting an old world powermac to netboot. So my question is this: Can
you netboot a beige G3 powermac with Debian? If so, how? 

note: I do not need to know about setting up dhcp, tftp, nfs, etcetera.
I just need to know the old world Powermac specific stuff. Like open
firmware settings, which kernel, intrd to use, etcetera. Thanks. 

Second Question: 

My second question is with respect to clusters. I did a little research
on OpenMosix and Mosix not too long ago, and my curiousity was genuinely
piqued. I was unable to find any mention of anyone ever creating an
OpenMosix cluster on PPC hardware however. Rather, my Internet searches
seem to have revealed that Mosix and OpenMosix were for x86
architectures only. Is this the case? Does anyone know of anyone running
an OpenMosix cluster on PowerMacs? 

Third Question: 

Does anyone know of any "OpenMosix like" clustering software for Debian
PPC? Specifically old world power macintosh? 

A pre-emptive thanks to those who offer up the answers: Thanks.
