Hi Ben!
Here are my test results:
Kernels tested:
* Linux 3.16.7-ck2 and Linux 3.18.0.
Hardware tested:
* Apple Mac Mini G4 (Radeon 9200)
* Apple Powerbook G4 (Radeon 9600 PRO Turbo)
* Apple iBook G3 (Rage Mobility 128 AGP)
Results before changes:
* Graphics broken on Apple Mac Mini G4, both kernels, out-of-the-box,
can be fixed by appending "video=radeonfb:off".
* Graphics broken on Apple PowerBook G4, both kernels, out-of-the-box,
can be fixed by appending "video=radeonfb:off".
* Graphics work on Apple iBook G3, both kernels, out-of-the-box.
Changes:
* CONFIG_FB_RADEON=y was changed to CONFIG_FB_RADEON=m.
Results:
* Graphics work on Apple Mac Mini G4, both kernels, out-of-the-box,
no additional kernel parameters required.
* Graphics work on Apple PowerBook G4, both kernels, out-of-the-box,
no additional kernel parameters required.
* Graphics work on Apple iBook G3, both kernels, out-of-the-box.
Remarks:
* Backlight dimming control works on both laptops in this
configuration. Brightness can be dimmed from 0% to 100%
smoothly. No other side effects observed, graphics and
display controls on both laptops and the Mac Mini work
as expected.
Conclusion:
* Please set CONFIG_FB_RADEON=m on powerpc32.
