A choice allow you to select multiple values if the type of all
choice entries are of type 'tristate' but this gets enabled
only when CONFIG_MODULES equal to 'y'.
So except if you really need the 'select multiple' when MODULES
are selected I see no easy way to achive what you want.

I did not try but carefull usage of 'depends on' could also help you
but it will get messy quite fast.

Maybe Roman can se a better way?
