the issue is does it have T&L capabilities. Supposedly the 915 integrated graphics does, so you shouldn't have the chesire cat/ black ground issue. However i would serisously do some checking around on the forums to be sure.
With 128MB of ram your performance is going to be absolutely terrible. I would go with at least a gig.
I have the 845g integrated graphics, and something like 700+MB of ram, and altough i do have the chesire cat (used the workaround for the terrain) problem, i am actually able to play decently. A little choppy, and somewhat slow in the end game. This is on huge map with 15+ opponents.
So I would say you shouldn't have a problem running the game as long as you upgrade your ram
