VRAM woes

Well, I managed to get my RAM back from the people downstairs, but NWN2 still doesn't run well...apparently the game wants 128 megs of VRAM at a minimum (256 recommended...I mean, c'mon, who has 256??) and I only have 64, and since I have a laptop, I get the impression it would be exceptionally difficult (or just exceptionally costly) to upgrade it.
