99% of the time a distro will give you an SMP kernel anyway.
Makes no difference w.r.t functionality if youve only got one.

When the machine boots it will detect another and bobs your
uncle. If - like me, you enjoy the pleasure of kernel poking,
then you might need to enable this, and you might to recompile
and re-install etc - but its not a big issue for me and the likes.

WinXP needs prodding to use the 2nd CPU if you upgrade thus,
but Win2K3 does - as indicated find that extra one itself.
