Check out the CC2420 data sheet. The TinyOS 1.x stack uses hardware-generated acknowledgments. Software processes received acknowledgments. The 2.x stack also uses hardware-generated acknowledgments. The Boomerang stack uses software-generated acknowledgments. If you're digging into the CC2420, I *strongly* recommend getting a developer's kit. They run about $600, but have software that lets you inspect every packet sent out, which lets you really easily figure out if a problem is in the receiver or in the transmitter.
