Sorry for the late reply, I've been taking a break from mailing lists lately.

To solve this problem, I opted to apply a patch (by Brian Masney -
http://home.ntelos.net/~masneyb/) to ISC DHCP which allows me to store my
dhcpd config in ldap.  I currently only store host entries in ldap keeping
the rest of my config in flat file format, so that it's easier to manage
with cfengine.

Once the data is in ldap, it's absolutely trivial to add host entries
while the dhcp server is running using a perl ldap module.  A nice side
benefit of adding host entries this way is that a dhcpd restart is not
needed.
