I'm not pleased with iBooks either, but have to code for it the way it is until it catches up with the way things ought to be. I only have two books on the iBookstore, and in both of them I've included a note to the reader saying specifically that it will look best on an ipad that uses iOS 6 and at least iBooks 2.2 .
I've had to "dumb down" the book I'm working on right now to deal with iBooks shortcomings. It pissed me off to have to make the changes but that's what I did.
Best,
Chuck
