There's pretty much nothing you can do except buy a new video card. There were some manufacturers who made cards that claimed to have 64 mb of RAM but it was only done through a driver trick where they actually only had 32 mb of physical memory. If you purchase a card through a well known manufacturer (BFG, Leadtek, eVGA and others) you will not run into this problem again.
