You can skip swap altogether and use MFS (memory filesystem) like Brian 
mentioned for other high write partitions that don't need to be 
persistent (/tmp, /var/log). See the following article on the website about using solid state storage:

Keep in mind though that Brian's setup was for slave nameservers that 
would be caching from another master. If your nameserver is acting as 
master, you'll be storing your records on flash since you need 
persistent storage, but I don't imagine those files will be write intensive.

Also, if you make /var/log MFS, you'll want to have an external syslog 
server set up ;)
