Actually, it doesn't anymore. I've sent a few books via Calibre to iBooks and the margins have been fine. I've been putting that down to something of the ebooks themselves... but I just sent one which I knew to have HUGE margins and which I subsequently read in Stanza. Looking at it now... the margins are fine. I rather think that Apple paid attention to this aspect of things and has made it so iBooks will not impose margins but will respect the publisher's margins instead.
