I had plans implementing some parts of that code on Freescale eval boards (HCS08 + MC13192 radio). I know several guys implemented some 802.15.4 code on MC13224v boards. Probably one of the low hanging fruits would be to implement HardMAC support for Philips SRM 7500 dongle. It implements 802.15.4 protocol over USB and it is already reverse engineered (http://sourceforge.net/apps/mediawiki/srm7500-linux/index.php).
