My opinion on this is that drivers should only be verbose if you ask them
to be. Under FreeBSD, everything is very quiet unless you specify the
"-v" boot flag. So, the FreeBSD aic7xxx driver spits out two lines per
adapter, and the SCSI system spits out two lines per device by default:

ahc0: <Adaptec 274X SCSI host adapter> at 0x1c00-0x1cff irq 11 on eisa0 slot 1
ahc0: aic7770 <= Rev C, Twin Channel, A SCSI Id=7, B SCSI Id=7, 4 SCBs
(ahc0:0:0): "QUANTUM PD1225S 3110" type 0 fixed SCSI 2
sd0(ahc0:0:0): Direct-Access 1169MB (2395980 512 byte sectors)

Dan Eischen mentioned something about using different syslog levels to
get this type of effect under Linux.
