The following is a boot log for a 64 bit port of Linux for IBM's 64 bit
PowerPC processors. This log was made on a pSeries model 270 which uses
a POWER3 microprocessor.

Impressive. One question, though --

You have 4 CPUs?

...or just one CPU?

(And when do we get XFree86 support for the GXT-2000P, -3000P etc?)

The controller can handle 8 CPUs.

The (native) 64bit port can handle only one CPU right now.

Thats the power3 kernel in 32bit emulation mode for that 64bit CPU.

Olaf pretty much answered all your questions. Yes we are running a
non-SMP kernel at the moment, but even non-SMP kernels need to place
an SMP's unused processors in a spin loop so they don't play havoc
with the system.
