What is the difference between mini6410_lcd_timing and real6410_lcd_timing?
In my opinion, it would be good as follows:

+static struct fb_videomode real6410_lcd_timing = {
+	.left_margin	= 8,
+	.right_margin	= 13,
+	.upper_margin	= 7,
+	.lower_margin	= 5,
+	.hsync_len	= 3,
+	.vsync_len	= 1,
+	.xres		= 800,
+	.yres		= 480,
+};
