I would suggest looking at gallium (src/gallium/include/pipe for API btw gallium & driver). The high level API like OpenGL go through a lot of common code before hitting the driver, classic mesa hw driver are bit harder to understand than gallium hw driver. Gallium offer a "clear" interface btw the higher level API (OpenGL, OpenEGL, OpenVG, ...) and the hw driver (src/gallium/include/pipe) thus i believe they are easier to understand (you can then choose to look into src/gallium/driver).
