the easiest thing to do would be to KEEP the dhcp on the ultra.  on the
linux gateway, try adding something similar to the following to your
/etc/dhcpd.conf file:

# /etc/dhcpd.conf
default-lease-time 21600;
max-lease-time 43200;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
option routers 192.168.1.1;
option domain-name-servers xx.x.x.xx, xx.x.x.xx;
option domain-name "your.domain.name";

subnet 192.168.1.0 netmask 255.255.255.0 {
        range dynamic-bootp 192.168.1.10 192.168.1.100;
        range dynamic-bootp 192.168.1.150 192.168.1.200;
}

host ultra5_hostname {
        hardware ethernet 8:0:20:f0:f2:1f;
        fixed-address 192.168.1.201;
        option host-name "ultra5_hostname";
        option domain-name "your.domain.name";
}

the key here is the  "option host-name" parameter in the static
assignment for the u5.  this will give the solaris machine the hostname
info that it is looking for at boot time.
