I know exactly where your coming from- I also have a notebook with an Integrated gfx card. It's a Dell Inspiron E1505 and let me tell you, it's probably THE worst thing to have as a gamer.
However, your in for some luck. I have Diablo 2 LOD and play it all the time, it works fine, it's smooth as long as you have a good internet connection. Warcraft 3 and Starcraft also work fine, I installed Warcraft 3 last week and I was unsure if it was even going to work, but it does. I don't think the gfx are up to par as I thought it would be, but it might be a gfx setting thing...I just don't know how to change that lol.
It also runs games like Counter-strike 1.6 and Day of Defeat fine too.
Heres a good site to refer to if you want to see if your notebook can run some games or not:http://www.srtest.com/referrer/srtest
There's a bunch of games listed on there; only drawback is that you need to actually be using the machine your trying to check for, since it scans your current computer that is connected to the site. It's not 100% accurate, I'll just say that right now. It ran some games that it said it wouldn't, so just use it as a tool to roughly estimate.
I really wouldn't sweat it, I remember I was in the same boat as you were last summer when my uncle was ordering my notebook. I was so scared he was going to get the crummiest vid card (which he ended up doing lol) and I was so scared that it wouldn't be able to run games
