This works fine for me in Ubuntu Intrepid, so I'm not sure why it wouldn't work
for you:
$ ifconfig wmx0
wmx0 Link encap:Ethernet HWaddr 00:1d:e1:02:37:89
inet addr:68.25.50.212 Mask:255.255.255.255

$ route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
99.207.212.72 0.0.0.0 255.255.255.255 UH 0 0 0 wmx0
0.0.0.0 99.207.212.72 0.0.0.0 UG 0 0 0 wmx0
$
And launchpad bug 139217 is either invalid or has already been fixed, as my
/sbin/dhclient-script does the following starting at line 194:
ifconfig $interface inet $new_ip_address $new_subnet_arg \
$new_broadcast_arg $mtu_arg
# point to point
if [ "$new_subnet_mask" == "255.255.255.255" ]; then
for router in $new_routers; do
route add -host $router dev $interface
done
fi
for router in $new_routers; do
route add default dev $interface gw $router $metric_arg
done
