+What is sm712fb?
+=================
+
+This is a graphics framebuffer driver for Silicon Motion SM712 based processors.
+
+How to use it?
+==============
+
+Switching modes is done using the video=sm712fb:... boot parameter.
+
+If you want, for example, enable a resolution of 1280x1024x24bpp you should
+pass to the kernel this command line: "video=sm712fb:0x31B".
