I can't help you directly. Just add on to your comments. I recently tried to cgd 
a ccd device with little success. Sometime it would work for a little (pretend), 
most of the time just complain about superblock even right after newfs, and 
quite regularly just lock the machine up.

It is quite straight forward to reproduce.
