I have a "lenovo 3000 c200" notebook. I want to use a graphic card accelerator. I wonder if exists a PC Card (PCMCIA) graphic accelerator like NVidia GeForce or ATI Radeon.
If it's an ExpressCard then there is connectivity for PCI-E x1. You could in theory therefore take something like this PCI-E x1 9500GT card a make a homebrew adapter for it. (Or even use x8/x16 card with it: like this guy did). Slightly risky proposition really and I'm not sure it's worth it, but it might be a fun project and you'd probably get a slashdot story out of it.
