Load balancing? I worked for a company that had over 500 users with over
400 PC's using DHCP in 60 different offices around the country and never
had a load problem running a single DHCP server on a 1.5Ghz Intel
Celeron. As far as "highly available" the server is either available or
you have network issues preventing it from being available.

Search again or give them a call as they are there.
http://www.onlamp.com/pub/a/bsd/2003/05/01/FreeBSD_Basics.html is just
one of several links to configuring a DHCP server available.

Also have you tried Google? Found this
http://www.madboa.com/geek/dhcp-failover/ using "dhcp failover" linux
as the search criteria.
Setting up a cluster is another option.
