Is the firmware bug specific to DVD media/volumes or would something like 
this affect any CD inserted?

The reason I ask is that if I insert a regular iso9660 CD-R disk, it is 
detected correctly by HAL, IVMAN, and KDE (I get the nice CD Icon on my 
desktop). Seems this happens only if I insert a DVD-R.

Here's the relevant lshal section (notice fstype and fsusage is correctly 
detected):

udi = '/org/freedesktop/Hal/devices/volume_label_000913_1339'
  info.udi = '/org/freedesktop/Hal/devices/volume_label_000913_1339'  
(string)
  info.product = '000913_1339'  (string)
  volume.disc.is_svcd = false  (bool)
  volume.disc.is_vcd = false  (bool)
  volume.disc.is_videodvd = false  (bool)
  volume.disc.is_rewritable = false  (bool)
  volume.disc.is_appendable = true  (bool)
  volume.disc.is_blank = false  (bool)
  volume.disc.has_data = true  (bool)
  volume.disc.has_audio = false  (bool)
  volume.disc.type = 'cd_r'  (string)
  volume.size = 24743936  (0x1799000)  (uint64)
  volume.num_blocks = 48328  (0xbcc8)  (int)
  volume.block_size = 2048  (0x800)  (int)
  info.capabilities = {'volume', 'block'} (string list)
  info.category = 'volume'  (string)
  volume.is_partition = true  (bool)
  volume.is_disc = true  (bool)
  volume.is_mounted = true  (bool)
  volume.mount_point = '/media/hdc'  (string)
  volume.label = '000913_1339'  (string)
  volume.uuid = ''  (string)
  volume.fsversion = ''  (string)
  volume.fsusage = 'filesystem'  (string)
  volume.fstype = 'iso9660'  (string)
  block.storage_device = 
'/org/freedesktop/Hal/devices/storage_model_QSI_CD_RW/DVD_ROM_SBW242C'  
(string)
  block.is_volume = true  (bool)
  block.minor = 0  (0x0)  (int)
  block.major = 22  (0x16)  (int)
  block.device = '/dev/hdc'  (string)
  linux.hotplug_type = 3  (0x3)  (int)
  info.parent = 
'/org/freedesktop/Hal/devices/storage_model_QSI_CD_RW/DVD_ROM_SBW242C'  
(string)
  linux.sysfs_path_device = '/sys/block/hdc/fakevolume'  (string)
  linux.sysfs_path = '/sys/block/hdc/fakevolume'  (string)

If this is a DVD specific firmware issue, I can certainly try commenting out 
and recompiling to see what happens. If it isn't specific to DVD, then 
perhaps something else is broken in the HAL software?

Thanks
