The online racing simulator
hardware vertex shading and AA support
I wouldn't bank on being able to use AA at all on an 845G without totally killing your frame rate (which TBH I'm surprised is high enough for you to want to consider AA). The 845G also doesn't support vertex shaders, so you'd need to upgrade to a dedicated graphics card if you want that.
For screenshots of LFS with all these effects (AA and AF, as well as the vertex shaders) applied, head into the thread named "How to make LFS look better". It has some rather nice screenshots
