I applied the patches of cko5 (which are on top ck6) to ck8, but I dropped supermount as I now use ivman.
series
patch-2.6.11-ck8+cko5.diff.bz2
split-out-2.6.11-ck8+cko5.tgz
The patches are to be applied on top of linux-2.6.11

Yesterday I stumbled across ivman, which has often been praised as the successor of supermount. I just emerge it and it worked witout any configuration. When I access the mount point (/media/cdrecorder) it automatically mounts the drive.
Sometime I will also find out how to prevent it from modifying fstab and mount the drives as non-root.
