This has been an issue for a long while in the alsa-driver CVS tree and
now is an issue in 2.5.4-dj2: the only snd-seq-* module to be built is
snd-seq-oss.o, the rest of them are not built at all. Under the ALSA
CVS tree I could build them manually, correctly - they were just skipped
over in "make all." I suspect this is a trivial Makefile issue, but I
have not found it in what time I have spent on it.
