If you want to create a closed-source library, which linked to Qt, you need the commercial license of the Qt, because you can only link to GPL-libraries, if your program is GPL-compatible.
This situation is a bit different, because the closed-source library *strictly needs* the Qt and can't function properly without it. ReactOS on the other hand doesn't require these 3rd party drivers and links to them dynamicly. Also this issue was already discussed (see the ros-general mailing list archives) even with Richard Stallman's comments.
