Here is another list:

WRT54G
CDF0 = WRT54G v1.0 / ADM6996L Chipset / CPU 125Mhz
CDF1 = WRT54G v1.0 / ADM6996L Chipset / CPU 125Mhz
CDF2 = WRT54G v1.1 / ADM6996L Chipset / CPU 125Mhz
CDF3 = WRT54G v1.1 / ADM6996L Chipset / CPU 125Mhz
CDF5 = WRT54G v2.0 / ADM6996L Chipset / CPU 200Mhz
CDF7 = WRT54G v2.2 / BCM5325EKQM Chipset / CPU 200Mhz
CDF8 = WRT54G v3.0 / BCM5325EKQM Chipset / CPU 200Mhz
