This 3D card is in fact supported, I've heard of it working on other brands of laptops, but the motherboard appears to be somewhat "nonstandard" in that the kernel agp chokes on it. I realize that this is an isolated problem, but I'm willing to test, debug, and provide output for any that
need it.

Using the fix described here:

AGP is properly initalized, and DRI works.
