You didn't say what bus type of cd & dvd you have, so I'm going to 
assume that they are IDE (or PATA in the new lingo). Speak up if they 
are actually SATA devices

Nothing to do with your disks, but why this setting?
You seem to have a 64bit Opteron, not a MkI pentium

maybe this one is more suitable for your hardware

You could try this one as a module and see if it works

At first glance your .config looks ok, so make sure those modules are in 
fact loading.

And we should check that the devices haven't changed names meanwhile... 
The major/minor numbers will be the same, so run ls -al and grep for 
these strings:


"3,  0"
"22,  0"
"33,  0"

and anything else you might find relevant in 
<kernel-sources>/Documentation/devices.txt
