Clone devices

How does one implement SVR4-style clone devices in Linux?

I'm trying to emulate a driver that uses /dev/fooclone to get a new
`instance' of /dev/foo, and I want to be able to set the minor number
in the file returned by my open() routine to correspond to the
/dev/foo instance I'm allocating to the process.

Something analogous to /dev/ptmx in SVR4...

Any ideas? I couldn't find any examples of this in the existing
drivers, but that could be my fault.
