|Don't take this as a insult, but the problem is your lack of knowledge, if you can't solder a new socket on and be done with it, you probably can't figure out the rest. (that was a insult, wasn't it?)|
You would need to clock bits into the display using some sort of display chip. I don't know if this has been covered, but you could do a search on the I-Opener forum.
If the display holds the bits on for you, you could shift them in using the parallel port and a routine you write in Linux. If not, and most LCD drivers are just that, bit drivers, then you must refresh them from some sort of memory and this is easy when you use a chip that does it all for you.
If you had specs on the display, and knew a good simple chip that would refresh for you, you would have it made.
If you were really a hacker, you would figure out how to manipulate the IC on the IO by cutting it's databus and address lines and connect them to the websurfer bus and control it from the surfer.
Since people have found a display driver for Linux, if you had source for the driver you could change the address in the driver to point to the IO's driver chip you wired up.
For more info on drivers and datasheets use the search feature.
If you got boored of being a half ass hacker, then you could hook the X, Y and clock inputs to the surfer's parallel port (or put it on a I/O address line!) and shift stuff into the display using a software refresh. You would probably get flicker, but you could make a cool lowres display if you doubled up scanlines. Make a color organ or something.
