I do need device-mapper, since I put /usr and /var on LVM filesystems. I
use ptkcdvd to copy data to CD-RW. I can remove this one.

Anyway, this patch from Andrew fixed the problem :
http://lkml.org/lkml/2005/2/23/214.

So I won't try to remove pktcdvd and device-mapper driver (except if you
_really_ want me to do so).

Thanks for your interest.
