Yesterday I started keyboard model compatibility page on fd.o. The idea is to have a list of (all) real models compatible with existing xkeyboard-config models. People who use (in X configuration) a model different from the real keyboard name - I kindly ask you to update that table (only if all keys on your keyboard work as expected). Please keep the alphabetic order whenever possible.
Also, from this table it is easy to see that most of the keyboards do not have geometry descriptions (I know, it is just a decorative thing but still ...). Contributions are mostly welcome, as always. I realize, creating geometry description is not a picnic (and I cannot recommend any tools) - but some people still manage it.
