So, part of the complexity is that your Promise controller offers both
SATA **and** PATA.

Well, the breakdown is this:

atapci0 = Promise FastTrak RAID
	--> ata2 (SATA)
		--> ad4 = Maxtor 6Y250M0
	--> ata3 (SATA)
	--> ata4 (PATA)
		--> ad8 (master?) = Maxtor 6Y120P0
		--> cd0 (slave?)  = TSSTcorp CDDVDW SH-S223F SB00

atapci1 = VIA 6420 SATA
	--> ata5
		--> ad10 = Seagate ST3300622AS
	--> ata6
		--> cd1 = LITE-ON DVD SOHD-167T 9S19

atapci2 = VIA 8237 ATA133
	--> ata0
	--> ata1

cd0 showing up attached to ata4 (somehow) is indicative of a problem.

It might also help if you could provide "atacontrol list" output.  I
assume DFBSD has atacontrol.

Makes perfect sense.
