    [PATCH] Updates to rivafb driver · 5a32c854

    The patch updates rivafb to the following:
    
    1.  Fixed cursor corruption and simplified cursor code.
    
    2.  Maximized var->yres_virtual on initial mode setting.  Scrolling,
       therefore, defaults to y-panning which is significantly faster.
    
    3.  Restricted var->xres_virtual and var->yres_virtual to 0x7fff
       (hardware limitation?).  Otherwise, var->yres_virtual > 0x7fff + panning
       will hang the GPU.
    
    4.  Added I2C/DDC support.  This feature enables independent mode setup
       to rivafb.  'stty rows n cols n' should now work correctly.  This is a
       configurable option.
    
    5. Various/minor fixes to drawing code.
