OpenGL Bug in AMD E-350 (Brazos) Driver

The old AMD E-350 catalyst driver unable to display a simple triangle rendered in OpenGL, even though the shader requested in the GLSL input is version 1.50. However, the driver did pass Geek3D's GPU Caps Viewer tests for OpenGL 4.0 support, the driver also capable of running combined OpenGL and OpenCL sample application from AMD APP SDK v1.4. Perhaps the problem is only on the GLSL compiler in the driver. I'm now using this driver version:
Driver Packaging Version	: 8.871-110627a-121536C	
Provider	                : ATI Technologies Inc.	
2D Driver Version	        :	
2D Driver File Path              :/REGISTRY/MACHINE/SYSTEM/ControlSet001/Control/CLASS/{4D36E968-E325-11CE-BFC1-08002BE10318}/0000	
Direct3D Version	        :	
OpenGL Version	                :	
AMD VISION Engine Control Center Version : 2011.0627.1558.26805	
with this driver, everything worked as expected and I've just noticed that the OpenGL support now increased to OpenGL 4.1. The previous driver only supports up-to OpenGL 4.0.
