"da#" devices always attach to "scbus#" devices, which in turn attach
to "ata#" devices. The extra layer is important so you can represent
all the busses of a multi-channel SCSI adapter. "camcontrol devlist
-v" is the best way I've found to list what attaches to what.

First, you don't want two sets of da0 hints :) This should work:
hint.scbus.0.at="ata1"
hint.da.0.at="scbus0"
hint.da.0.target="1"
hint.da.0.unit="0"
hint.scbus.1.at="umass0"
hint.da.1.at="scbus1"
hint.da.1.target="0"
hint.da.1.unit="0"
