Not in master anymore, but agreed, we are talking Danny here IIRC.

Ah yes. I do recall a nuance of a package with mixed kernel modules and
userspace code.

The new module-split class from master would handle this nicely, so
taking inspiration from master's would would probably be an even
shorter route to getting something working.
