Are you sure that hal doesn't read them any more? Nothing substantial
changed in hal since 9.04. (Nobody really works on it any more)

My first guess would be that it just seems like it, since GNOME isn't
using hal at all any more. Can you check lshal whether your volume has
volume.ignore==True?

For the convenience of other readers:

 <device>
  <match key="volume.label" string="Bluebirds">
   <merge key="volume.ignore" type="bool">true</merge>
  </match>
 </device>

The modern counterpart would be to write a custom udev rule which sets
DKD_PRESENTATION_HIDE. Check /lib/udev/rules.d/95-devkit-disks.rules
for examples. Putting this into /etc/udev/rules.d/95-hide-bluebird.rules would be the
DK-disks equivalent of your rule:

ENV{ID_FS_LABEL}=="Bluebirds", ENV{DKD_PRESENTATION_HIDE}="1"
