I tried adding this to my dhcpd.conf and the dhcpd (version 3.0.4)
server accepts it without a problem. Perhaps you have a subtle typo in
there?

subnet 10.10.0.0 netmask 255.255.224.0 {
  option routers 10.10.0.1;
  pool {
    range 10.10.16.0 10.10.31.254;
  }
}

Can you post the exact error message and the section from dhcpd.conf?
