Will there be an option to ignore the BIOS and do something like the
current system?  I'm all for paying attention to the BIOS, but I've got
over 75 Xeons in my cluster and if they have the wrong BIOS settings,
this is going to hurt when we switch to 5.x.

Overall, I'm looking forward to this change.  The death of the SMP
kernel is something I've been looking forward to for a long time.
