Help! RDPDD Chained DD is video card? Shows up as ATI 5700 Series in DM

[fisto]

Hello all,

New here, trying to mine with a ATI 5770 on Windows 7 32-bit.  I have tried everything I can think of to get this card to show up in GPU Caps Viewer / GUIMiner / Python.  It is labeled in dxdiag and caps viewer as a "RDPDD Chained DD."  In Device Manager it correctly displays as a 5700 series card.

I have tried the OpenCL SDK 2.1 and 2.4 with 10.4 and 11.6 drivers respectively.  I have also removed any remnant of nVidia I could find (though I don't think this computer ever had nvidia drivers installed).  Couldn't find a working copy of driver sweeper 2.1 so I couldn't go that far.

Any ideas? 

Thanks in advance

Bump, I have this problem with another miner now too!  This one is an AMD 6870, it is also labeled as RDPDD Chained DD in GPU Caps and doesn't show up in any miner.

Someone else must have experienced this if I have on two completely different systems.
