commit 2e1868b560315a8b20d688e646c489a5ad93eeae

DRI trunk-20040613 import
the X server supports drm 1.1, and doesn't even call this ioctl any
more. When reviewing this note that for hilarity both the
kernel-internal functiosn (set_busid) and the libdrm wrapper
(drmSetBusid) have names not matching this ioctl (SET_UNIQUE).
