Well, I was looking at the DX manual - I confess I'm waiting to lay my mitts on one, which should be landing in my corner of Europe today.
If you're talking of the 6" e-ink screen (I have one of the Hanlin ones, branded BeBook), I do not think there's a good way of reading PDFs "printed" to Letter/A4 on them. (Thus the DX.)
(Short, of course, of intelligently reflowing the PDF to a smaller page size - which currently seems to be an opportunity ;-)
