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 ...
