: Hi Warner,

: why not do it the other way round? Keep them out of GENERIC, but have
: loader(8) load some of the most used modules (snd_driver!) per default.

: That way, people can easily disable these (without needing to
: recompile).
: 
: I mean, what point is there in the whole KLD infrastructure, if we are
: going to add every device into GENERIC anyway?

Because the meta-data necessary to know which module to load doesn't
presently exist in a standardized enough form to make this a viable
option.  Each driver does its own thing to match the cards, and
there's no easy way to know that any given usb device needs module
foo.
