Hmmm, we have currently two entries registered for CPU modules we
use in a number of internal projects.  Though we're happy to
share the code for these modules, we never intended to propose it
for mainline (as nobody alse can use these modules).
What do you propose for such cases?
Do you have a block of numbers for "private use"?
