Hmm, this was definitely the wrong way to fix. The file opt_i4b.h
is created by config(8) and put in the kernel compile directory.
It contains preprocessor symbols which in turn are used to control
the inclusion of source.  Your ``fix'' effectively excluded all
low level driver source and caused the breakage during
loading the kernel.

Sorry, I don't know how to feed the NetBSD configuration to make
it create opt_i4b.h. For FreeBSD this is described in FreeBSD/INSTALLATION,
step 8. This one liner is the content of my opt_i4b.h:

#define TEL_S0_16_3 1
