Some of those props are RO, IIRC.
Some might be RW but contextual (i.e., won't work outside of a reader Booklet).
But, if you don't actually rely on the UI at all, it's
a standard Linux fb ioctl away 
. (Actual mapping will be device-specific, to a potentially large extent, though [i.e., don't expect 0 to mean UR, on your device or any other]).
(Otherwise, doing that behind the UI/Xorg's back is a great way to shoot oneself in the foot (as in, soft-locking pillow and/or awesome). There's another recent-ish thread about that somewhere around here).
