Anyone?

I have all of the current VGA drivers for my Mobility Radeon HD 5870 (G73JH-A2 Asus Laptop) and SDK 2.1 installed but GUIMiner won't detect my OpenCL device. SDK 2.4 won't install correctly or at all for some reason and I'm thinking about trying SDK 2.3 for trial and error. Is there anything I might be missing or should I try using a different mining program?
