Multiple screens aren't done with Xinerama any more. xrandr is the new
way.

Don't know about r128 specifically, but that's an old-style xorg.conf.

Rework your xorg.conf, example below.
Notes:
Only one Device section for a single video card.
Overall screen size defined as Virtual:
For side-by-side: (monitor1X + monitor2x) X max(monitor1y,monitor2y)
1024+1920 x max(768,1200) = 2944x1200
Monitor positions on virtual screen set in Monitor sections.
Monitor/video connectors set in Device section.
Don't know if AccelMethod EXA works on r128.
