Well I'm not mentioning to change sdXc to mean anything else, just
trying to make it able to use it in ccd (like it can be used for
regular BSD filesystems)....

 * Grep for RAW_PART in /sys to see where sdXc is special.  It's special
 * before a label exists (then it's the only partition than can be opened)
 * and after a label exists (then the label on it is write protected ...).

Ok, but does that mean anything in terms of using sdXc as a regular
filesystem or as part of a ccd?

 * 
 * I use /dev/rsds1 partitioned normally and /dev/rsds[2-4] essentially
 * unpartitioned (I have to put a label on them to keep newfs happy but
 * mount handles arbitrary block devices with a supported file system
 * on them).

So you are saying it's ok to use sdXc, right?
