Not yet.

Would be nice...

The thing is: I can't make it work on gentoo easily. My distro's devs are not 
going to support it as well, because "latest upgrade of mdm is 2+ years old". 
(http://bugs.gentoo.org/45833)

Maybe I try dedicating a day just for MDM and succeed, but there are questions 
like:

1. should I patch libX11(-6)?
2. is /etc/init.d/mdm non-executable in debian?
3. ... others I can't think of right now. 

Well, let me know, what you think about those things first!
