I think the problem here was the DRI2 tiling fix, which was great for
the 915-class 3D performance regression but bad for 915-class 2D.  I've
pushed a fix to master that should help.  If it does, I'll try to get a
2.6.3 out soon.

    Only allocate pixmaps aligned for tiling when requested by DRI2 GetBuffers.
    
    This saves massive quantities of memory on pre-965 since the DRI2 tiling
    enable caused the minimum size of any pixmap to be 1MB.
