If you have KDE installed, use ksnapshot.
I am not aware of any tools that do this except in X. However, you can always throw your own code in-that is if you have the time and need to expirement.
You will need to first capture the video memory as a bitmap and use the libraries for converting it to PNG. I assume libpng has such facilities.
