DVD drive not detected

I am currently using 8.0-BETA4 amd64 and I noticed yesterday that my
PC's internal DVD reader/writer is not detected at boot time.  I'm not
sure whether or not this was the case with BETA3 since I don't use the
drive all that often.  It was certainly working ok with 7.2-STABLE
though.  I have copied and pasted the messages from dmesg.boot below,
in case that is of help in diagnosing the problem.  If I remember
correctly, it used to appear as /dev/acd0.

Thanks in advance for any suggestions.
