Re-configured it?  You should build it from the port.

Did you do a full buildworld?  If you just changed your kernel, that won't
do.

Okay, what happens when you try the following:  (with the same CD in the
drive that you were trying to mount)

camcontrol tur cd0 -v
camcontrol inquiry cd0

If those don't work, you didn't do a full buildworld.

If they do, and the mount isn't working, it's likely you're having trouble
with the recent disk/slice changes.  I'm not sure how to fix that, someone
else will have to speak up and explain.  Most likely syncing to a more
recent -current would fix it.

Is there anything that shows up in the dmesg when you try to mount the CD?
