Log Message:
Use the hardware scaler to do overscan compensation. You can set the
scaling value as a percentage in two ways -- either as a kernel cmdline
parameter (fb.scale=<pct>) or at runtime with sysctl (hw.genfb0.scale=<pct>).

Setting scale=100 disables the scaler, any other value enables it. For
the cheap TV on my desk, scale=95 gives me a fully visible framebuffer.
