o.k., thank you.  it wasn't related to any specific group, 29 was just
an arbitrary example in this case.  same problem appears with allcaps
or whatever.

the culprit is the "capability" module, which must not be loaded when
trying to load realcap, apparently (since selinux allows just one
secondary security module).  the "capability" module is needed
e. g. for ntpd, in order to drop root privs.  fortunetaly, the realcap
module has the same effect, it just has to be loaded before ntpd.  i
changed the /etc/rcx.d/ link from S87realcap to S57realcap in order to
do this.

thanks a lot!
