I am amused (annoyed at Amazon?) that people think the Kindle supports PDFs. Adobe created PDF to have a portable way of exactly representing documents. The Kindle converts PDF documents into HTML as best it can, and sometimes it does well enough. But PDF has Postcript rendering as an embedded capability, and HTML does not. All the math symbols in a book I am publishing (which I have in PDF format) do NOT convert either with Amazon's Kindle converter, or Adobe Acrobat 8's HTML converters. In other words, I would have to find all the unconvertable parts of the book and manually create images out of them. It's not what I call PDF support!
