I don't know about the actual errors you're getting, but I've got BIND9 (9.2.1) 
and dhcpd 3.0pl1 working together with dynamic DNS updates of dhcp clients.  I 
know I had some trouble originally setting it up and the trick was the following 
entries in my /etc/dhcpd.conf file:

# DHCP 3.0.1 /etc/dhcpd.conf

# The 3 lines below support Dynamic DNS updates
ddns-update-style interim;
ddns-updates on;
allow-client-updates;
authoritative;

Also, you may need to make sure the rndc.key referenced in your /etc/named.conf 
is valid.

I agree.  There's very little documentation on the web that covers setting this 
up, but surprisingly, the man pages are pretty thorough -- 'man dhcpd.conf' in 
particular.

Good luck.
