Looking at latest xdm from modular.xorg, it has two Xservers:
config/Xservers.ws.cpp (workstation) and config/Xservers.fs (file server).

This is based on the --with-config-type=ws or =fs switch. The default is 
"ws".

The "ws" Xservers file does have the needed line. So at least in the near 
future this problem will be resolved :)

Also, I didn't see any rc.d/xdm script. When we create the new x11/xdm 
package we need to make sure to include that (x11/xdm/files/xdm.sh) too.

If someone needs this fixed now (in xorg-clients), maybe submit PRs for 
these issues.
