+ * voffset - framebuffer offset in MiB from aperture start address. In order for
+ * the driver to work with X, we must try to use memory holes left untouched by X. The
+ * following table lists where X's different surfaces start at.
+ *
+ * ---------------------------------------------
+ * : : 64 MiB : 32 MiB :
+ * ----------------------------------------------
+ * : FrontBuffer : 0 : 0 :
+ * : DepthBuffer : 48 : 16 :
+ * : BackBuffer : 56 : 24 :
+ * ----------------------------------------------
+ *
+ * So for chipsets with 64 MiB Aperture sizes, 32 MiB for v_offset is okay, allowing up to
+ * 15 + 1 MiB of Framebuffer memory. For 32 MiB Aperture sizes, a v_offset of 8 MiB should
+ * work, allowing 7 + 1 MiB of Framebuffer memory.
+ * Note, the size of the hole may change depending on how much memory you allocate to X,
+ * and how the memory is split up between these surfaces.
+ *
+ * Note: Anytime the DepthBuffer or FrontBuffer is overlapped, X would still run but with
+ * DRI disabled. But if the Frontbuffer is overlapped, X will fail to load.
+ *
+ * Experiment with v_offset to find out which works best for you.
