Believe it or not, no debug kernel was generated, either.
So for some reason, a kernel config that has always generated a kernel.debug 
and an install process that have always backed up my kernel did neither.  
Something must be seriously hosed here.  Any ideas as to what that could be?

I've been running with the closest CPUTYPE I can since I switched to FreeBSD 
(which was ~2yrs ago), and haven't had any bugginess to speak of, much less 
panics.  I'll try backing that out all the same.

I've got a semiworking kernel on the machine now, and I'm working on 
recompiling the errant kernel with DDB enabled.  I'll post the results.

Thanks very much!
