    Subject[PATCH] bttv_card & bttv_radio (was Re: BTTV detection broken in 2.4.0-test11-pre5)
    Gerd Knorr wrote:

    Well, I see the modules vs. static flame war is already in progress ;-)

    My reason for wanting static kernels is that I usually build many, very
    different versions of the same kernel, among which I frequently switch
    back and forth, and which I copy to different machines. Modules just get
    in the way here.

    I'm not at all against modules in general, quite to the contrary, but
    there are cases where a static kernel is preferrable, and since it's
    easy to keep the driver usable also without modules, I think it's worth
    the effort.

    Since we don't have Keith Owens' wonderful extension yet, I've made a
    patch for 2.4.0-test11-pre7 that adds the new option bttv_card, and
    renames bt848_radio to bttv_radio, replacing my previous patch. It also
    fixes a rather embarrassing mistake I made in the bt848_radio patch ...
