    Don't know if this can be relied upon, but on an aging box at home
    that has a "Western Digital Caviar SE WD800JB 80GB 7200 RPM
    8MB Cache IDE Ultra ATA100 Hard Drive", I see:

                 % prtpicl -v | grep devid
               :devid id1,cmdk@AWDC_WD800JB-00JJA0=WD-WCAM94142920

    Which looks like the truncated identifier seen with dmesg:
            % dmseg | grep 'Disk[01]' | tail -2
            Jul 8 15:38:37 anza gda: [ID 243001 kern.info]
                    Disk0: <Vendor 'Gen-ATA ' Product 'WDC WD800JB-00JJ'>
            Jul 8 15:40:50 anza gda: [ID 243001 kern.info]
                    Disk1: <Vendor 'Gen-ATA ' Product 'ST36450A '>
