Bingo. Ok I am enlightened. this one isn't actually hal's fault.

Perhaps. The problem is that some of the other file system code looks
at the _end_ of the disk. Unfortunately CD-R doesn't have an "end" it 
sort of tails out into no-mans land. Most drives politely handle such
requests, some don't. The ide-scsi driver has the needed magic to work 
around some of this, ide-cd lacks it.

The HAL fix I guess would be to only try iso9660/udf on CD-R/CD-RW media,
but it might ultimately be better if we can fix it kernel side.
