Yesterday I booted my Windows System again on my Lenovo Thinkpad Edge E520 (with intel sandy bridge + AMD Radeon HD 6630M), to see whether there are some updates that tackle the Switchable Graphics problem. (Even under Windows the graphic card switching was buggy, and did not work at all for OpenGL applications. Hence the chance that there would eventually come an update was at least > zero )
And to my surprise there was indeed a BIOS and graphics driver update, that enabled manual switching of the graphics adapter. However switching doesn't take place in the BIOS, but using the catalyst control center. This was a huge improvement, at least under Windows. But what does this mean for linux? Of course I tried my luck, and there was indeed some advance for the linux crowd. I have some good and some bad news. I installed the fglrx 11.11 driver, obtained from the AMD website. Good News: After that, switching, using the amdconfig tool for Power Xpress, was possible! (Yay!!) Bad News: I was not able to get a running Xserver. When starting X, a segmentation fault occurs. But nontheless, X detected both cards sucessfully, and I expect that the seg fault may be caused by previous (failed) attempts to get the card running. This was only a quick shot, I did not spent much time on fixing this, but I think there is finally light at the end of the tunnel.
