This is a different problem. You should re-make the acd devices. This
is a result of changes to the ATA code that changed the minor mode of
the 'c' device inode from 2 to 0. Just:
cd /dev
rm acd0*
./MAKEDEV all

Then acd0c (and acd1c if you have two CDs) will work. This happens if
you don't run mergemaster or did not choose the option to re-make your
devices after running it when the change in MAKEDEV took place.
