Perhaps I have been leading you on a wild goose chase. I have re-read
all of your posts and I now understand that you want to wire down bus,
target and unit. 

It is my understanding that the device.hints will wire down the device
(i.e. /dev/sa# or in my case /dev/da#). I played around with my system
with the external firewire drive and as long as I have the lines in
device.hints the 0-0-0 is reserved for the drive whether it is plugged
in or not. The optical drives remained at 2-0-0 and 2-1-0.

I then plugged in a USB thumb drive and rebooted. This forced the
optical drives from 2-0-0 and 2-1-0 to 3-0-0 3-1-0 respectively.

I then plugged in a USD card reader and rebooted. This forced the
optical drives to 4-0-0 and 4-1-0.

I thought about this for awhile and looked at dmesg again. I then
edited /boot/device.hints as follows

### Wire down external hd to da0###
hint.scbus.0.at="sbp0"
hint.da.0.at="scbus0"
hint.da.0.target="0"
hint.da.0.unit="0"

hint.scbus.1.at="ata1"   #optical drives on the second ata cable.
hint.cd.0.at="scbus1"
hint.cd.0.target="0"
hint.cd.0.unit="0"

hint.cd.1.at="scbus1"
hint.cd.1.target="1"
hint.cd.1.unit="0"

this forced the optical drives back to 1-0-0 and 1-1-0 no matter what
other devices are plugged in.

This may be what you want.

I hope this helps.

P.S. I am adding the list back in.
