dmesg will tell you what's getting recognized at boot time.

dmesg | grep cd

That will strip out some of the irrelevant bits.   You should see 
something like:
acd0: DVD-R <TDK DVDRW0404N> at ata1-master PIO4


I find that invalid arguments frequently mean that the cd isn't a data 
cd, but rather an audio cd, or there is no cd in the drive.  It's a 
data cd?  You can skip the optional arguments and just:  mount /cdrom  
if the entry is in fstab (which default installs usually have).
