You don't need "device cd" in your kernel. It is only needed for SCSI
CDs and yours is clearly ATAPI.

I would be interested in the result of:
ls -l /dev/acd*

FWIW, the "mount -u /" is no longer required. It is implicit in the
"mount -a -t ufs", but it should not hurt.

You might also want to add:
hw.ata.atapi_dma="1"    # Run the CD-ROM/DVD in DMA mode
to /boot/loder.conf.

I'm really running out of ideas!
