Unfortunately laptop upgrades can be pretty limited. Most have the graphics chip soldered to the motherboard, so an upgrade requires replacing the whole motherboard and possibly the cooling system and CPU also. I haven't done an exhaustive search, but nothing I've looked at so far indicates that the MS2384 is any different. If that's something you want to pursue, you might be able to find a replacement board on eBay.
It's possible that you could hook up an external graphics card, but getting the drivers straight can be a major hassle and the performance increase usually isn't worth the trouble.
If you want help working out a motherboard/GPU solution, let me know and I'll try to help you track down compatible components. For that I would need the exact model number which is usually on a data sticker or plate on the bottom of case, or inside the battery compartment. (MS2384 is a series number.)
