I then scan for the access point from my laptop: it does not show up.
However, ifconfig now shows some packets received by wifi0:

A few such packets come in every time I run "iwlist scan" on the (remote)
laptop.
dmesg is silent through all this.
This hardware configuration has worked in the past with ubuntu dapper's
madwifi-old.
This morning, I got the card working---with some 2.6.17 kernel and some
recent madwifi version, I do not know exactly---but I have never
reproduced that success, which only happened one time while I was invoking
all sorts of wireless-configuration commands.
