askyn, what firmware are you on? I am on 15.3 beta, and the
Hacked Adobeviewer does preserve all the formatting (with the "standard" one I have problems with the fonts), at least as far as I can see.
EDIT: a lot of useful information is provided by Jackie adn rkomare in
this thread (yes, it was on the Pro models, but the info on CSS is "general")
