That pdf refers to another one: 
http://wiki.seeed.cc/Grove-OLED_Display_0.96inch/
There's an fbdev driver that supports ssd1305, ssd1306, ssd1307 and ssd1309:
https://www.kernel.org/doc/Documentation/devicetree/bindings/display/ssd1307fb.txt
http://elixir.free-electrons.com/linux/latest/source/drivers/video/fbdev/ssd1307fb.c
Maybe the ssd1308 will work with that driver...
