Did you get xserver/os/privsep.c rev 1.25 ? Since I did the commit at
the same time I was writing the mail, it may take a few hours more to
get make it to all the cvs mirrors.

did you create all the /dev/tty[EEF]0 devices with MAKEDEV this time ?
In my tests I created explicit display sub-sections too. Generally the
xorg.conf parser is a bit flakey in this area, and rejects some
configurations for no good reason
Here's the working xorg.conf I used (with privsep.c 1.25) for 2
devices:
Some parts may be useless, but since it took some fiddling to get this
working I stopped there.
