Why doesnt Unity 4.3 let me play with Intel(R) gma 3100 which was released in 2007

Graphics: Removed support for pre-DX9 GPUs on PC. That is, GPUs made before 2003 (NVIDIA), 2002 (AMD) and 2004 (Intel) will not be supported now.

that is what unity said, for the new update.
But Intel is not 2004. Mine is 2007 and it still has this problem. It was released at the same time DX9 so why is the DX9 error still showing up when I try and play a unity game?
thanks.

If you believe your card meets the requirements but is not supported, submit a bug report with full details: operating system version, GPU model, driver version etc.
