I can perfectly reproduce the problem with a completely different setup
(Sony USB burner), with cdrecord failing while device permissions are
correct. By making cdrecord setuid root, things work again.

This is a serious regression from the sarge version, in which the setuid
bit is not needed.

Cheers,
