Thanks! This was giving me a headache previously.

Eventually this can be extended by an example how to set up
.git/gbp.conf so that it does export the git tree and run the symlink
dance automatically? This works for me:

[git-buildpackage]
prebuild = find -type l | while read dest; do src=$(readlink -f $dest);
rm $dest; cp $src $dest; done
export-dir = ../build-area/
tarball-dir = ../tarballs/

Also it would be nice if README.source would have a link to
http://pkg-xorg.alioth.debian.org/
(and eventually other places with XSF packaging related information)
- this probably applies to all packages managed by XSF. Makes it easier
for non-XSF people to start hacking X properly :-)

Something I didn't find so far are instructions how you would like to
get patches submitted.

Some minor updates for http://wiki.debian.org/Xorg:
* wheezy has xserver-xorg-core 1.11
* In the "Video Drivers" section, can you add a link to
  http://wiki.debian.org/NvidiaGraphicsDrivers?
  (This page mainly talks about the non-free driver).
