FYI, just in case it's of any use to you, there is a patch at

	http://people.freebsd.org/~iedowse/cam_xccb.diff

that was an attempt from a while back to separate the userland and
kernel CCB structures to avoid breaking the ABI when making such
changes. I wasn't sure if this was a sensible way to go for CCBs
though, and the resulting code is a bit gross, so I didn't take it
any further.
