I went through the entire xorg-server distribution and aggregated all
the licenses I could find (except the questionable GPL files, see my
last mail).
There are many many permutations on essentially the same license terms,
but I have been pedantic and treated slight differences as separate
licenses.
Here is a description of the process I used:
tar xvjf /usr/portage/distfiles/xorg-server-1.1.1.tar.bz2
cd xorg-server-1.1.1
find -name '*.c' -o -name '*.h' | xargs gvim
egrep -Rli "permission|copyright" * | grep -v "\.[ch]" \
| grep -v "\.in$" | xargs gvim
cd ..
tar xvjf /usr/portage/distfiles/xorg-server-1.3.0.0.tar.bz2
