No, I meant the EMC modules that use RT support.  That would be
something like one of the following, from the .ini file :

; Name of motion control program
; EMCMOT =  steppermod.o
EMCMOT =  stgmod.o
; EMCMOT =  stg8mod.o
; EMCMOT =  emcmotsim

Maybe all you need to do is remove the lines that look like :

# Install RT-Linux scheduler module, if it's not installed
if ! /sbin/lsmod | grep rtl_sched 1> /dev/null 2> /dev/null ; then
  /sbin/insmod -f /usr/src/rtl/modules/rtl_sched
fi

from the run.xxx file, as this would be a redundant thing to do, if
the module was permanently installed.
