	You're using MP Spec version 1.1, not 1.4.  From my own, and other
folks' experience, you probably need to enable MP Spec version 1.4 in your
BIOS in order for the SMP kernel to work.  (This isn't always the case, but
with newer motherboards, it definitely seems to be...)

	So, go into your BIOS, find the option that lets you change the MP
Spec version, and change it to 1.4.  Send mail back to the list and let us
know whether this fixes your problem..
