     The ssdfb driver provides wsdisplay(4) support for OLED/PLED framebuffer
     modules based on one of the following controller chips:

              Solomon Systech Ltd SSD1306

              0x02: Generic SH1106 modules using default settings

              0x03: Adafruit Industries, LLC product 938 (128x64)

     Some modules can be reconfigured to attach via spi(4), typically by
     moving surface mount zero ohm resistors.  This is currently not
