Hang them off of the device that the console belongs to?

Classes and busses are almost identical except:
- busses is the binding of a driver to a device (usb, pci, etc.)
- classes are usually userspace interactions to a device (input,
tty, etc.)

So this sounds like a class to me.

If you want me to review this, I'll be glad to so do once 5.1-rc1 is
out...
