Looks like a problem with your setup.  It appears you are using the r300 3D
driver rather than the r600 3D driver.

egl is probably using the wrong driver.

--- Comment #7 from Benjamin Franzke <benjaminfranzke@googlemail.com> 2010-11-23 11:36:58 PST ---
diska is using egl_gallium which differentiates between r300 and r600 in
drm-mode using the function "is_r3xx" provided by
winsys/radeon/drm/radeon_drm.h

This function just checks a range of pci ids, the evergreen ids lay in the
range:
static INLINE boolean is_r3xx(int pciid)
{
    return (pciid > 0x3150) && (pciid < 0x796f);
}

Thats why state_trackers/egl/drm/native_drm.c loads pipe_r300.
