Quick post from my phone -- existing PCMCIA card cages from random laptops are a dime-a-dozen on fleaBay, if you want to go that route. They would likely need minor modifications to the keying, but that's hardly a showstopper.
Ron, did you see my previous email? I have an LCD panel that may work for you, to replace the original in the Eee - but I won't know if it's compatible, without that part number. If it *is* compatible, I'll ask you to cover shipping costs and that's all. I know /almost/ for a fact that my display will work with an EOMA68 card, as it takes a parallel TTL input -- somewhere I think I have the datasheet -- I just need your part number to know if they are physically interchangeable without getting out the craft knife... I suspect the aspect ratios are different, though -- mine is straight SVGA (800x600), and IIRC, Eee PC netbooks were always widescreen -- either 800x480 or 1024x600...
