What about going the LinuxBIOS table way, providing an array of writes

typedef struct { 
        device_t dev;
        unsigned pos;
        unsigned and_val;
        unsigned or_val;
} modifier_t;

and then provide two arrays of modifier_t for enable_shadow and
disable_shadow.

or whatever the according s-record representation will be in future ;-)
Then we're on the safe side without hurting philosophy.
