You can always create your own my_phy.ko that just contains my_phy.c
and kldload it into a kernel that already has 'device miibus' either
via kld or statically compiled.

Not unless you want to statically compile it into your kernel.  If you
want to do that you will also have to update sys/conf/files.

Not that I'm aware of.  Maybe I'll sit down and write down what I know.
