Hello there,

finally....! I got a running version of xphoton for modular-xorg-server. It took me some time to create the patch. Be 
warned, this patch will kill your old xorg installation (if you had one running yet).

1. cd into your modular-xorg-server directory (e.g. cd /usr/ports/x11/modular-xorg-server)

2. "bmake clean" first, because I needed to change some things on the build environment

3. Delete your old Xorg installation if you have one (e.g. pkg_delete xorg-server-1.6.3)

4. Download the attachment and apply it on the directory (patch -p0 < xphoton-for-modular-xorg-server.patch)

5. bmake

6. bmake install

7. Run with Xphoton - the rootless X server will now run with many debug messages

8. Start xpdf in another console (tested), xmore (tested), xcalc or some other basic X applications

Have fun and please test it. The patch and the code are party hacked down but I did not have much more time. I hope 
he're some interested people :-)

Best regards,
André Wösten
