It's not possible, some graphics cards use system RAM for extra memory and even that's painfully slow compared to video RAM.
For example, a lot of laptop cards don't actually have any video memory at all. They just use a certain amount of system RAM. This is why most laptops are horrible for gaming.
Remember though, Video RAM isn't everything though, I've seen low end x300 cards with 512 megs of RAM on them. even though it has all that memory it'll still run games like crap just because the GPU is slow.
