Well, to quote the frequent posting to this newsgroup,
If the question is of a general nature, ... ask
FreeBSD-questions. Examples might be questions about installing
FreeBSD or the use of a particular UNIX utility.
If the question relates to enhancements to FreeBSD, and you can
make suggestions about how to implement them, then send the
message to FreeBSD-hackers.
If the question is of particularly technical nature, such as
implementation details or suggestions for improvements, then send
the message to FreeBSD-hackers.
I think this qualifies as one of the last two, so -hackers is the place.

As you say, the Magic Garden is for System V. BSD is a little
different, though not too much.

Yes.

UTSL. And -hackers. There's some stuff in section 9 of the manual,
but it's not quite the level of completeness you'd find in the ddi/ddk
docco.

UTSL. And -hackers. In particular, the PCI drivers are in
/usr/src/sys/pci.
