Are those real small caps? They look like fake ones to me -- compare for instance with Libertine (http://www.tug.dk/FontCatalogue/libertine/libertine.pdf).
I'd expect all TeX fonts to have small caps available, but it seems that would be a mistake. 
Package pxfonts, for example, uses Palatino and there small caps look as expected (http://www.tug.dk/FontCatalogue/palatino/palatino.pdf), however, I'd really like a bit "blacker" font. Bitstream Charter (packages charter & mathdesign) has math support as well, but small caps, unfortunately, look like fake ones.
Is there any font similar to Utopia with a solid math support there and real small caps as well? I wouldn't mind using Libertine one bit, but I was not able to find any package or a \usepackage parameter that would load adequate math symbols and fonts.
Any help would be much appreciated.
