no cd0/pass0 devices under 7.0 (though acd0 is there)

Hi!

I didn't use my dvdrw drive for some time, and recently I've
discovered that there's no cd0 and pass0 devices in /dev, though
acd0 is there and works well. Before all three devices were present.
Not sure, but it may be that I didn't use cd/pass after moving to
7.0 from 6.1, so maybe they've disappeared after the upgrade.

My system is FreeBSD 7.0-RELEASE i386, drive is
acd0: DVDR <NEC DVD RW ND-3520AW/3.07> at ata0-slave UDMA33

all devices under SCSI peripherals secrion are enabled in the kernel
config:
device          scbus           # SCSI bus (required for SCSI)
device          ch              # SCSI media changers
device          da              # Direct Access (disks)
device          sa              # Sequential Access (tape etc)
device          cd              # CD
device          pass            # Passthrough device (direct SCSI access)
device          ses             # SCSI Environmental Services (and SAF-TE)

(AFAIR, only scbus, cd and pass were needed).

What can I do to bring cd0/pass0 back?
