Fundamentally I think we have at least three separate bugs here.
First, the lack of support for 0866 cards. There's several bug reports upstream about lacking support for 9400 cards, such as fdo #19545, however none mentioned 0866 specifically, so I've filed an upstream bug with this request: https://bugs.freedesktop.org/show_bug.cgi?id=23044 and subscribed Mario (Jerone, you'll need to subscribe yourself since you seem not to be already subscribed to the freedesktop.org bug tracker). Please follow up with upstream with any info or testing they need with this hardware.
