+/* Interface history:
+ *
+ * 1.1 - ??
+ * 1.2 - Add vertex2 ioctl (keith)
+ *     - Add stencil capability to clear ioctl (gareth, keith)
+ *     - Increase MAX_TEXTURE_LEVELS (brian)
+ * 1.3 - Add cmdbuf ioctl (keith)
+ *     - Add support for new radeon packets (keith)
+ *     - Add getparam ioctl (keith)
+ *     - Add flip-buffers ioctl, deprecate fullscreen foo (keith).
+ * 1.4 - Add scratch registers to get_param ioctl.
+ * 1.5 - Add r200 packets to cmdbuf ioctl
+ *     - Add r200 function to init ioctl
+ *     - Add 'scalar2' instruction to cmdbuf
+ * 1.6 - Add static agp memory manager
+ *       Add irq handler (won't be turned on unless X server knows to)
+ *       Add irq ioctls and irq_active getparam.
+ *       Add wait command for cmdbuf ioctl
+ *       Add agp offset query for getparam
+ * 1.7 - Add support for cube map registers: R200_PP_CUBIC_FACES_[0..5]
+ *       and R200_PP_CUBIC_OFFSET_F1_[0..5].
+ *       Added packets R200_EMIT_PP_CUBIC_FACES_[0..5] and
