The first patch is used for modify integrated palette RAM for gamma-correction of the data stream. Let Graphic data absolutely passes through the Gamma Correction RAM. Special for Screensaver Operation. It will improve the gamma operation.
The second patch is used for fix the Rotate operation (exaOffscreenAlloc method), Deled prepare allocate mechanism. Use exaOffscreenAlloc allocate the shadow buffer. Rotateeddata has to be allocate in offscreen memory range.
Graphic memory >=10Mb (In BIOS setup)
*Ubuntu Bugzilla #377929
