Sure, and I've acknowledged that. But it doesn't mean this needs a kernel solution.

So use Eric/Arjan's program that does it in 60ms -- you get a dynamic /dev, no initrd, fast boot, and no kernel changes required.
It remains to be seen how much it costs to do it in user space vs kernel space. Arjan -- do you have a pointer to your program? Perhaps I can shake loose some time to test that.
