I'm the one who wrote the support for that device when I was working for SSV embedded systems. What I made is a kernel driver that operates a 320x240 monocrome SED1335 in text mode. PicoGUI can set the graphics mode with the standard ioctls, similar to the frame buffer console. You should try to find the required kernel patch at http://www.ssv-embedded.de/ (the device is called trm916, the patch should be included in the DIL/NetPC kernel RPMS). If it's not there (yet), write me again. The hardware connection we used is the general purpose i/o of the AMD Elan processor, but parallel port should do because you only need 9 output pins (strictly, 1 address output and 8 i/o but input is not needed for the PicoGUI driver, only for device detection). The kernel driver sets a lot of magic register values that depend on the type of your display (the sed133x is a rather generic controller), most importantly the resolution. You will have to experiment a lot with these to get any output. From there on, the rest is trivial. Having the official controller documentation is a great help, but I'm not sure if I have it somewhere in case you need it. Good Luck!
