/usr/src/sys/compile/VESUV # make yields:

[...]
loading kernel
identcpu.o: Undefined symbol `_i486_bzero' referenced from text segment
*** Error code 1

Compiling the SMP-GENERIC kernel works.
When I take identcpu.o form SMP-GENERIC, the new kernel runs, too!

uname -a:

FreeBSD vesuv 3.0-RELEASE FreeBSD 3.0-RELEASE #0:
