I'm currently not at the location with the network without a DHCP server,
but IIRC I tried that already and it didn't help.
It also seems to me that my problem is a bit different:
In my case dhclient gets its "lease", but doesn't configure the interface
according to it if it is a static lease (and not a lease received from a
DHCP server):
If there is a DHCP server everything works:
nobby:/etc# /etc/rc.d/netif start
DHCPDISCOVER on sis0 to 255.255.255.255 port 67 interval 4
DHCPOFFER from 192.168.2.1
DHCPREQUEST on sis0 to 255.255.255.255 port 67
DHCPACK from 192.168.2.1

ether 00:c0:9f:28:24:60

If there isn't a DHCP server (simulated in my home network by shutting the
DHCP server down):
nobby:/etc# rm /var/db/dhclient.leases.sis0
nobby:/etc# /etc/rc.d/netif start
DHCPDISCOVER on sis0 to 255.255.255.255 port 67 interval 4

No DHCPOFFERS received.

As you can see, dhclient seems to "get" the static lease but doesn't
correctly bind to it in the latter case.
