Im not sure to how many types of hw FreeBSD has been
ported, but the POWER4 processor (Apple's G5) has
something called a hypervisor on top of which the unix
kernel runs. The hypervisor  has some facilities for
partitioning, migration of resources etc.. So, it
isn't exactly a case of dumb hw in all cases.
