@ USvER - Were you ever able to resolve this?

I have tested all versions of blender form 2.61 to 2.65 both x86 and x86_64.
This is what i have discovered on Windows 7 (64) with HD6850(Barts) GPU and latest AMD drivers (released 17.01.2013):
Display Driver ver. 9.012
OpenCL(tm) Driver ver. 10.0.1084.4

When rendering with GPU:
2.61: solid ligthgray color, like there is no geometry
2.62: geometry with ambient occlusion, solid light gray color
2.63: solid black color (at this version blender switched to rendering block by block and not the whole scene as in previous versions)
2.64: blender hangs on loading kernels
2.65: OpenCL no longer supported as a rendering device

Sad story ='(
