FreeBSD on Xserve?

Why do you think that 970 does not have BAT registers?
There are 16 special purpose registers specifically to implement Block Address Translation.
I don't know what's a story with fan-drivers. Personally, I was under impression that G5 has liquid cooling system.
Not that should be a major show stopper for FreeBSD support of G5 boxes.
AFAIK, PPC port of FreeBSD is incomplete, but moving ahead quite fast.
If original author wants to mature OS with MAC and SMP support SELinux might be a good candidate.
However, Linux does not have jails. Only other OS that has them is Solaris 10 which does not run on PPC.
I am not sure what kind of stack protection was referred in the original email. OpenBSD has propolis, but I was under impression there is no such option in FreeBSD. I recall that it was decided that security by obscurity will not make it into the kernel.
