It would be nice, if we can get it into the kernel. If it's not possible
for some reason, I still can add a partiton table parser to volume_id
and we can create child devices in HAL with 'block.session=<number>' and
add these to fstab.

Back to your DVD. What's in the first sessions partition table? Mine
looks like this:

Cool, thanks. So we keep it compatible with the klibc version in udev.
