It is MI (or if it is not it is a bug). I know it compiles on sparc and
alpha, but it has only been tested on i386. So I only added it to
Perhaps it should be added to other port's GENERIC too, but commented out ?

EXT2FS is a bad example for that, because I don't think pmax, arm32
or pc532 users want EXT2FS support by default in their kernel.

I don't think this is a good idea. We need a file with all the
config options or devices for a port. If this file is not GENERIC, then
you need to add the new option for all ports, plus <std-config>.
I can't see a win here.
