Do you know what the power consumption of a POWER8 chip is?

ARM and MIPS are load-store machines too, and usually much cheaper and
more power friendly. Sure powerpc has 32 registers and arm only has 16,
but so what? That's what each core has and many things have multiple
cores these days. Mips has 32 as well.

ARM chips certainly exist that are 64bit and run that kind of speeds.
Not sure what speeds mips are at these days but it has had 64bit versions
for a long time.

I have no idea what BSD has to do with this, but then again I am not
sure what you are even trying to describe.
Besides have you heard of kvm? Virtual machines are a commodity these
days and simple to do.

Well OLPC certainly seems to have been a flop done by someone without
a clue what actual problems needed to be solved.

I wish it had made sense what I read, but it did not.
