65 * - Add getparam ioctl (keith)
66 * - Add flip-buffers ioctl, deprecate fullscreen foo (keith).
67 * 1.4 - Add scratch registers to get_param ioctl.
68 * 1.5 - Add r200 packets to cmdbuf ioctl
69 * - Add r200 function to init ioctl
70 * - Add 'scalar2' instruction to cmdbuf
71 * 1.6 - Add static agp memory manager
72 * Add irq handler (won't be turned on unless X server knows to)
73 * Add irq ioctls and irq_active getparam.
74 * Add wait command for cmdbuf ioctl
75 * Add agp offset query for getparam
