I'm also adding optional JPEG output to the next version of Mangle, that should help alleviate some storage issues on the space-starved Kindle 2
I used a 256-shades of grey test pattern to find out. And then took a screen shot of it on my K2.
Kind of obviously, the palette ends up being #000000, #111111, #222222 ... #ffffff
Not so obviously, only 15 shades of grey are rendered (both on the K2, and in the screen shot image). For whatever reason there's no #eeeeee. And if I make a 16 color image, again only 15 are rendered.
