Just curious here. As of about two, maybe three weeks ago, I was able
to boot DragonFly on my P4 HT machine with an SMP kernel.  I just did a
fresh install of DragonFly BSD 1.0A and now can not boot an SMP kernel.
Was there a "simple" change that caused this that could perhaps be
reverted or was it a major sub-system import that will require much more
