 I tested on real hardware:
 
 cd0 at scsibus0 target 6 lun 0: <TOSHIBA, XM-5401TASUN4XCD, 3485> cdrom removable
 
 With yesterdays install CD image:
 
 [  29.0000144] WARNING: cd0: total sector size in disklabel (856320) != the size of cd0 (214080)
 [  29.1000124] WARNING: cd0: end of partition `a' exceeds the size of cd0 (214080)
 [  29.1900134] WARNING: cd0: end of partition `f' exceeds the size of cd0 (214080)
 
 and nothing with todays. Disklabel looks like:
 
 # /dev/rcd0c:
 type: SCSI
 disk: optical media
 label: 
 flags: removable
 bytes/sector: 512
 sectors/track: 640
 tracks/cylinder: 1

 total sectors: 856320

 interleave: 0
 trackskew: 0
 cylinderskew: 0
 headswitch: 0           # microseconds
 track-to-track seek: 0  # microseconds
 drivedata: 0 
 
 8 partitions:
 #        size    offset     fstype [fsize bsize cpg/sgs]
  a:    853760         0    ISO9660       0             # (Cyl.      0 -   1333)
  f:      2560    853760     4.2BSD   1024  8192    16  # (Cyl.   1334 -   1337)
 
 
 I also tested on qemu and the messages are gone:
 
 # dmesg|fgrep cd0
 [     7.196135] cd0 at atapibus0 drive 0: <QEMU DVD-ROM, QM00003, 2.5+> cdrom removable
 [     7.215925] cd0: drive supports PIO mode 4, DMA mode 2, Ultra-DMA mode 5 (Ultra/100)

 [     7.282799] root on cd0a dumps on cd0b
 
 
 and disklabel says:
