	You're right,

	the swap, typically configured, is much more than the amount of the video memory, but in fact the swap is just a reserv, which ensures continuation of the normal operations on the machine, at times of peak loads.
	In our days the amount of RAM placed in the servers is so much, that the swap, in fact, is rarely used at all and a very small amount of it (several MB) is used. In that cases having a very fast swap space in the Video RAM, in addition to the disk swap, would be a good solution.
