Subject: What is the absolute minimum options for a kernel? (INET required)

I am trying to create a minimal kernel for debugging a boot problem
after the recent code merges in -current.  I tried the following
kernel file but got a undefined symbol netisr_set from
i386/i386/machdep.c (I commented out the reference to build the
kernel).
What is the minimal set?  If I add INET, I get other undefined unless
some devices/pseudo-devices are defined.  I have attached the config
file that I created.  Why is INET a required option?
