Ok. I've got it figured out now. Short answer: Put the following in
/etc/hal/fdi/policy/backup-disk.fdi (name the file whatever you want):

<?xml version="1.0" encoding="UTF-8"?> <!-- -*- SGML -*- -->

<!-- 
  System policy to not automount the backup disks.
-->
<deviceinfo version="0.2">

  <device>
    <match key="volume.uuid" string="09af9742-82eb-4520-86a8-0f2425d5f1aa">
      <merge key="volume.ignore" type="bool">true</merge>
    </match>
  </device>

</deviceinfo>

Add more <device> tags for additional volumes to be ignored.

It's not ideal, since volume.ignore means more than just "dont
automount". There is a storage level option called
storage.automount_enabled_hint which seems to be ignored. Ideally,
there'd be a volume.automount_enabled_hint to work on a per-volume basis
instead of a per-storage-device basis, but since the hint seems to be
ignored it really doesn't matter where it is :-)

Thanks for spuring me on to find this. Thank God for Free Software.
There's no more accurate documentation than the source code.
