Given that psmouse is monolithic and can't be [easily] split into
separate drivers (because they each protocol has to be actively probed),
I believe that allprotocols should be enabled by default. People who
really know what they are doing can reduce the size by compiling parts
of it out.

So copying what other protocols did was right ;)
