Seeking help persuading a desktop and laptop to talk to each other over a
private network (192.168.0.0).
The 'link' LEDs at both ends remain dark and no communication appears to be
taking place. Ping from either side results in 100% packet loss, and telnet
from either side results in 'No route to host'. It's just some silly
misconfiguration, I hope. More details below, all help welcome.

Desktop
-------
Mostly Slink plus upgrades to get to 2.2.14. It has two Linksys ethernet
cards. One connects to a DSL modem, the other to the laptop. The card
connected to the DSL modem works fine, the other doesn't. The result is the
same with the cards' roles swapped in /etc/network/interfaces, so I know that
both cards can work. Same with cables swapped, so both cables are OK.
netbase version is 3.18-1.
Here is ifconfig (eth0 is the 'dead' one):

Laptop
------
Mostly Potato. It has a Linksys PMCIA dual function network/modem card. While
impersonating the desktop (same fixed IP, etc) and connected to the DSL modem,
it works fine. When connected to the desktop (and after switching scheme) it
doesn't.
netbase version is 3.18-2.
