It was my impression, that the ddx was called "radeonsi" or at least "radeon" and not "ati".

Pretty sure, that doesn't do anything. But it may be necessary to put swrast there if it doesn't compile because of som stupid build system dependency. If not, Just a space character will be interpreted as an empty list, otherwise it will build some default like r300 I think.
