cdroms lost permissions

Mandriva is using pam_console; CD-ROMs permissions were set by /dev/cdrom* 
key; after last update removed /dev/cdrom%e (due ot deprecated status) cdrom 
devices are belonged to root.

The suggested pathc creates persistent entries for CD-ROMs in /dev/cd 
(actually $ID_TYPE). This allows easy matching by using /dev/cd/*/* as key.

This also clearly separates HDDs from CD-ROMs maing it easier to search for 
all available CD-ROM drives or HDDs (OK, with HAL it is irrelevant, but not 
every script is easy to convert to HAL interface).
