That's the attachment part, but the actual driver code doesn't live in 
dev/isa/lm_isa.c - it lives in dev/ic/lm.c which is not defined in any 
config 'files*' file.

For example (sources current as of yesterday):

        {335} cd /usr/src/sys/arch/i386/conf
        {336} cat TEST
        include "arch/i386/conf/GENERIC"

        lm0 at iic?
        {337} config TEST
        ../../../../dev/i2c/files.i2c:53: attaching undefined device `lm'
        *** Stop.
        {338}
