On my 8cpu, 4node machine, I can now disable arbitrary cpus, so that
the kernel comes up with anywhere between 1 to 8 cpus. I haven't run
a kernel compile in this configuration though. Neither have I tried
disabling cpu A on nasid 0 (as a special case).
I did shoot myself in the foot though by disabling node boards that
were the only routes to the console port via the baseio board (prom
appears to be a little stupid about this). I will have to pull boards
around tomorrow to get the machine back up.
Feel free to try enabling/disabling cpus (take care not to render
your system unbootable though).
