No, it's I who am confused, at least WRT file names.  :)   So, I started 
with a clean source tree.

I examined dev/isa/files.isa and found the following lines that handle 
the LM78 attachment to the isa bus:

        # LM78 temp/fanspeed monitor
        attach  lm at isa with lm_isa
        file    dev/isa/lm_isa.c                lm_isa

So I added the following lines to dev/i2c/files.i2c after changing only 
the attachment from isa to iic, and filename:

        # LM78 temp/fanspeed monitor
        attach  lm at iic with lm_iic
        file    dev/i2c/lm_i2c.c                lm_iic

My config file is as before:

        include "arch/i386/conf/GENERIC"
        lm0 at iic?

Yet config(1) still complains:

        ../../../../dev/i2c/files.i2c:53: attaching undefined device `lm'

It would seem that config(1) isn't pulling in the device definition from 
sys/conf/files in this case.

So I'm still confused as to why config(1) recognizes the lm device when 
attached to isa, but not when attached to iic.  Maybe I've just been 
staring at this too long...
