        I was wondering, because Samsungs cards should be supported by
the HostAP driver (which remind me, HostAP needs to go in the kernel).

        This analogy doesn't work. If your network is wireless, you
won't connect to it with an Ethernet card (and vice versa). A fully 64
bits userspace has only very minor downside, and most users won't see
any difference. If we follow your line of thought, we should all be
using a 16bit userspace on i386 (more compact, more compatible).

        It was backlogged, it seems to be catching up (but I need to
see if I find it).
