For some reason, you CD-R drive was connected to /dev/sda. That 
shouldn't happen with Ubuntu 8.04. What is the output of "mount"?

I noticed you commented out the part of your fstab that specifies your 
root partition. Why? Without fstab entries, your hard drive partitions 
and CD-R devices could be associated randomly with various moon craters 
and such.

Just kidding, but please show us the output of these commands:
mount
cat /proc/cmdline
uname -a
