OK, I've found the error!!!!
On the Xinit page, we have:
---
sed -e '/$serverargs $vtarg/ s/serverargs/: #&/' \
-i startx.cpp

for the Sysv/elogind book, while we do not have this for the systemd book.
Removing the ": #" allows startx to run the server and the usual clients.
I think even the suid-wrapper is not needed! (it drops privilege anyway if
/dev/dri/card0 is KMS compatible). This can be tested by moving
/usr/libexec/Xorg.wrap to /usr/libexec/Xorg.wrap.nouse, and trying again:
startx still works.
So we can:
remove the sed on the Xinit page
remove any enable-xxx-suid switch for xorg-server (well, maybe some drivers do
need the wrapper, this has to be tested, but I do not have the hardware (intel
driver works fine without the wrapper)).

PS: I've spend almost 24 h running the server, xinit, with gdb, playing with
xauth files, etc, before finding this stupid bug!
Must be old hardware for me then. I still work with the sed, but if
removing it fixes for everyone else, then excellet! From two working builds:
if [ "$have_vtarg" = "no" ]; then
: #serverargs="$serverargs $vtarg"
fi
Looking at it further, it probably always worked with libsystemd aware
dm (that if never would have evaluated to true unless started from the
command line).
Still slightly confused, but happier. :-)
