Success at last.  It may be that my real problem was not due to udev, but 
was because there was no DHCP client installed.  None of the docs I found 
made any mention of the need for such a thing.  But I installed udhcpc, 
and maybe that made a difference.

I went with an auto up and the name eth0 for simplicity.  For 
completeness, this was my setup:

offnode2:/home/cgm# cat /etc/network/interfaces
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
auto lo
iface lo inet loopback

# for DSL
auto eth0
iface eth0 inet dhcp

offnode2:/home/cgm# cat /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.

# PCI device 0x10ec:0x8139 (8139too)
SUBSYSTEM=="net", DRIVERS=="?*", ATTR{address}=="00:c0:26:6c:40:fc", 
KERNEL=="eth*", NAME="eth0"

Then I connected the DSL modem to power, the telephone line, and by 
ethernet cable to the computer, and rebooted.  Lo and behold, I have a 
fast internet connection!  Upgrading packages can be done in minutes 
instead of hours.  That's nice.

Thanks to all who offered advice and comments!
