This is not true.

Intel chipsets do support AP mode; what they don't support is 5 GHz AP.

You wouldn't want to run a 2.4-GHz-only router for any kind of real-world long-term use, but if you just want to start a quick-and-dirty 2.4 GHz AP for testing/hacking/reverse-engineering, Intel chipsets are very good for this because they have out-of-the-box support for channel-hopping to support simultaneous client+AP operation.
