radeon_vid new features:

 - tested UYVY format and known as working
 - YV12, I420, IYUV direct support
   (were missed: p23_blank_lines_at_top, p23_v_accum_init in
    radeon_vid_display_video - good info for Y800 support ;)
 - experimental support for Rage128/Rage128Pro chips

 16bpp, 24bpp and 32bpp pixel support compiled as modules).

+		      ====================
+		      
+Was designed for mplayer and currently can be used only by mplayer.
+It's RGB-YUV BES for radeon cards (althrough there is experimental
+support for rage128 / rage128pro chips).
+
+Installation:
+~~~~~~~~~~~~~
+
+After building modules just copy them to:
+/lib/modules/$(LINUX_VER)/kernel/drivers/video
+directory.
+Don't forget about: 
+depmod -a
+
+If you are doing it first time then create the device then execute
+following command:
+mknod /dev/radeon_vid c 178 0
+for radeon_vid.o
+mknod /dev/rage128_vid c 178 0
+for rage128_vid.o
+
+Using with mplayer:
+~~~~~~~~~~~~~~~~~~~
+
+Currently there is only way to use ATI's drivers:
+mplayer -vo vesa:lvo:/dev/radeon_vid -<your options> filename
+or
+mplayer -vo vesa:lvo:/dev/rage128_vid -<your options> filename
+
+Note:
+~~~~~
+You can pass only options with can be recognized by vo_vesa driver.
+(Indeed radeon_vid and rage128_vid are stupid things and can create
+video overlay only. But mode switching and other adjustement performs
+vo_vesa driver. This mean that they use VESA BIOS as graphics server).
+
+Conslusion:
+~~~~~~~~~~~
+This stuff (radeon(rage128)_vid) currently doesn't support any standards.
+So after implementing linux standards I'll fully rewrite this driver.
+
 Enjoy
