I have an Apple-branded 5870 and also have the same high temperature at idle, 61 degrees, with 10.8.3. No sure exactly what it was in 10.8.2, but I do not believe it was this high or I would have noticed it.
That sounds really very strange! Or Apple now uses the GPU as additional CPU to make their systems a little bit more faster ;-)
In the meanwhile I tried to use the ATI5000Controller.kext, AMDRadeonAccelerator.kext, ATIFramebuffer.kext and the ATISupport.kext from 10.8.2 but this results in a massive graphic issue without QE/CI - BUT with normal temperatures!
However - moved back the 10.8.3 kexts and just waiting for a solution or advice or whatever...
