Comment # 11 on bug 89730 from 
This also works but it looks like another variations on a theme - not
accelerated.

Section "Device"
    Identifier "video0"
    Driver     "nouveau"
    Option "ShadowFB" "on"
EndSection

Option "ShadowFB" "boolean"
    Enable or disable use of the shadow framebuffer layer.  Default: off.
    If this option is enabled, the driver will cause the CPU to do each drawing
operation first into
    a shadow frame buffer in system virtual memory and then copy the result
into video memory.
    If this option is not active, the CPU will draw directly into video memory.
    Enabling this option is beneficial for those systems where reading from
video memory is, on average, 
    slower than the corresponding read/modify/write operation in system virtual
memory.
    This is normally the case for PCI or AGP adapters, and, so, this option is
enabled by default unless acceleration is enabled.
