PyGame + PyOpenGl + ZBuffer?

[Max]

I've inserted the set_attribute, then verify it was set.

    pygame.display.gl_set_attribute(GL_DEPTH_SIZE, 16)
    pygame.display.set_mode((640,480), OPENGL|DOUBLEBUF )
    print "ZBUFFER:",pygame.display.gl_get_attribute(GL_DEPTH_SIZE)
    print pygame.display.get_driver()

The display.get_driver() displays "directx"... DIRECTX????!!!!! WHY??? Is it
normal?

Inside the draw loop, I test if the depth test is still working...
        print "Enabled: ",glIsEnabled(GL_DEPTH_TEST)

It's a simple scene with four GL_QUADS overlapping; two with z=0 and two with
z=0.5
        glTranslate(100,100,0.5)
        glTranslate(100,100,0.0)

with a depth range from 0 to 1
    glDepthRange(0.0,1.0)

BUT... the zbuffer isn't still working... also I get a very low framerate.

HELLLP!!
