have you? 

this package, available in rpmforge, shows considerably less than 
hal-device did, albeit in a somewhat cleaner output format... ..  

neither hal-device or lshw showed the serial of the optical devices on 
the 3 different random servers I tried them on.   lshw doesn't even show 
the serial on SCSI hard disk drives, which is available from several 
sources on the same machine.
