So I am slowly making progress. I had a look at the source code of the gnome-settings-dameon and found out that the maximum volume you can set with your media-keys is hardcoded... So much for an easy way to make it configurable.
One can still set it themselves, but I don't think that is a solution for many users. Anyway the setting can be found in
plugins/media-keys/gsd-media-keys-manager.c and then look for MAX_VOLUME.
A note of caution hower; as I haven't tried this myself yet, I have no idea what a sensible idea for a maximum volume is.
