Does this cause problems with the way things now are? If so, what are
they?
They are simple.
Suppose the pcspkr driver was loaded
by the udev. Then someone types:
modprobe snd-pcsp
and that doesn't print anything, so
he thinks the snd-pcsp was loaded and
asks me why there is no sound. :)
Only by typing "dmesg" you can see what
actually happened, but it would be better
to have that from modprobe too.

Does this change need to be backported to older -stable kernels?
I think it can't hurt.
