opengl ES SDK and graphics cards

Hi all,
I am new to openGL ES programming. I am using the SDK on linux platform and have a basic doubt about the libEGL and libLESv2. with “ldd” none of the above two shared objects shows any dependencies over graphics card drivers.
My doubt is that the using any emulator for openGL ES exploits the graphics card or not ?

Thanks in advance
