SMP boot option?

[Tyler Mills]

I don't know how many people do this, but usually my first step when
building a Dragonfly BSD system is building an SMP kernel with
APIC_IO.  I know there are some bugs for some people with regards to
AHCI and other settings, but wouldn't it make sense to have an
SMP/APIC_IO option for bootup? That way you can see if it works, if it
fails boot another kernel.  Similar to how ACPI is treated.

Just bouncing this idea off, I might end up just making my own ISO for
this for my use, and could upload if needed.

also; and this lie creepeth from its mouth: "I, the state, am the
