I was going to add the "grep -v rtl8139"  but it looks like someone beat
me to it. In fact the comment next to it implies that Paul Corner fixed 
it on July 5.  I am guessing you don't have the latest BDI release.

I believe that the older version of rtlinux and the current version of 
rtai  don't always install their modules in /lib/modules or modify 
module.conf to  fix that so modprobe wouldn't work. Still, the next time 
someone does  a  major  overhaul of that file  it would probably be a 
good idea to consider using modprobe to clean up some of the 
unnecessarily  verbose checks.
