The SA-1110 has on-board LCD, PCMCIA and memory controllers, but I'm not sure if the LCD controller is suitable for anything more than palmtop-sized screens. The all-in-one XScale would also be a great choice. 600MHz RISC OS laptop. Yum.
PC laptops use the PCI and AGP specifications but the devices are not normally removable. There's even a mobile version of the graphics processor used in the Iyonix available.
