You understand 802.1X authentication occurs BEFORE DHCP right? 802.1X being L2 doesn't require the client to have an IP address.  Some NAS support DHCP-Snooping which in turn can be used to add Framed-IP-Address to Accounting-Requests which you can then record in your database.
But this is NAS specific and absolutely nothing to do with FreeRADIUS.

It allocates IP addresses. I believe someone adapted it to work with the built in DHCP code.  It could also work with NAS which forward DHCP traffic as RADIUS Access-Requests.

Just use DHCP relays.
