The video card is built into the logic board and can't be altered. However, I do believe it is shared RAM so it takes some of your actual RAM and uses it as VRAM

No you cannot upgrade the card unless you want to replace the logic board with one that has the 128mb vram on it already.

@Gabe please research before giving false advice. The vram on the powerbooks have never been shared with the main ram!!!!!!, it is dedicated to the video card only!!

I never stated that that was a fact, I said that based on knowledge of mobile computers and their lack of discrete graphic cards.
