You can just use;
host laptop1.yourdomain.net {
option dhcp-client-identifier "laptop1";
fixed-address laptop1.yourdomain.net;
}

One would think incorrectly. The two terms are not anded together,
(either will work) so you will get that IP if you match the MAC or you
match the dhcp-client-identifier.
DHCP isn't a security method, if you want filter MACs then do it
elsewhere. If you want to get into really hairy configurations,
look at classing but I wouldn't recommend it.
This isn't a FreeBSD specific question, nor a -mobile specific
question, anyway. If you want isc-dhcpd configuration help, they
run an dhcp-users list.
