Hmm...okay, thanks.  I didn't look real closely when I made that.

I'll try the cold boot trick first to see if I can 'unstick' processor 1,
and rerun 'make config' to look at the serial options more closely.

Also, I tried the borg.mit.edu 2.2.10 multiprocessor kernel with no luck.
It just stopped after "booting..." on the inital screen.
