Another approach to fixing glDrawPixels might be to use the
_mesa_meta_DrawPixels() function from meta.c. Just plug it into the driver
dispatch table in savageDDInitSpanFuncs()

It seems like offsetting the aperture address fixes this issue. I am not sure
what is the proper place to do this, but this patch at least works for me. It
fixes drawpix and a lot

Is it possible that the frame buffer address gets wrongly calculated (because

It seems to me that the frame buffer written to is tiled, and that the

Just in case someone looks at it, in the above backtrace I had disabled the
fast_draw_rgba_pixels so the drawing is done by savageWriteRGBASpan_565()
through the "slow" path.

This is tested with latest 2.6.37 kernel, and libdrm 2.4.21.
