+config KS0108
+        tristate "KS0108 LCD Controller"
+        depends on PARPORT_PC
+        default n
+        ---help---
+          If you have a LCD controlled by one or more KS0108
+          controllers, say Y. You will need also another more specific
+          driver for your LCD.
+
+          Depends on Parallel Port support. If you say Y at
+          parport, you will be able to compile this as a module (M)
+          and built-in as well (Y).
+
+          To compile this as a module, choose M here:
+          the module will be called ks0108.
+
+          If unsure, say N.
+
+config KS0108_PORT
+        hex "Parallel port where the LCD is connected"
+        depends on KS0108
+        default 0x378
+        ---help---
+          The address of the parallel port where the LCD is connected.
+
+          The first  standard parallel port address is 0x378.
+          The second standard parallel port address is 0x278.
+          The third  standard parallel port address is 0x3BC.
+
+          You can specify a different address if you need.
+
+          If you don't know what I'm talking about, load the parport module,
+          and execute "dmesg" or "cat /proc/ioports". You can see there how
+          many parallel ports are present and which address each one has.
+
+          Usually you only need to use 0x378.
+
+          If you compile this as a module, you can still override this
+          using the module parameters.
+
+config KS0108_DELAY
+        int "Delay between each control writing (microseconds)"
+        depends on KS0108
+        default "2"
+        ---help---
+          Amount of time the ks0108 should wait between each control write
+          to the parallel port.
+
+          If your driver seems to miss random writings, increment this.
+
+          If you don't know what I'm talking about, ignore it.
+
+          If you compile this as a module, you can still override this
+          value using the module parameters.
+
+config CFAG12864B
+        tristate "CFAG12864B LCD"
+        depends on X86
+        depends on FB
+        depends on KS0108
+        default n
+        ---help---
+          If you have a Crystalfontz 128x64 2-color LCD, cfag12864b Series,
+          say Y. You also need the ks0108 LCD Controller driver.
+
+          For help about how to wire your LCD to the parallel port,
+          check Documentation/auxdisplay/cfag12864b
+
+          Depends on the x86 arch and the framebuffer support.
+
+          The LCD framebuffer driver can be attached to a console.
+          It will work fine. However, you can't attach it to the fbdev driver
+          of the xorg server.
+
+          To compile this as a module, choose M here:
+          the modules will be called cfag12864b and cfag12864bfb.
+
+          If unsure, say N.
+
+config CFAG12864B_RATE
+       int "Refresh rate (hertz)"
+        depends on CFAG12864B
+        default "20"
+        ---help---
+          Refresh rate of the LCD.
+
+          As the LCD is not memory mapped, the driver has to make the work by
+          software. This means you should be careful setting this value higher.
+          If your CPUs are really slow or you feel the system is slowed down,
+          decrease the value.
+
+          Be careful modifying this value to a very high value:
+          You can freeze the computer, or the LCD maybe can't draw as fast as you
+          are requesting.
+
+          If you don't know what I'm talking about, ignore it.
+
+          If you compile this as a module, you can still override this
+          value using the module parameters.
