if you look at the script network is run first, then wireless (if the card is a wireless one) > 2 - If I recall correctly, when I insert a pcmcia card (or when I resume > from suspend), cardmgr invokes a "cardctl insert" or something like > that.

They notify cardctl. cardctl looks up the card type inserted via /etc/pcmcia/config and inserts the proper module then runs the proper /etc/pcmcia script. > 3 - On a non-laptop that's going to use dhcp, I would configure for dhcp > in /etc/network/interfaces, no?

Recent pcmcia-cs packages have merged the functionality. You should be able to configure everything via /etc/network/interfaces now. Look at the end of /etc/pcmcia/network.opts. If it makes a call to ifup in start_fn() then you have this currently. The /etc/network/interfaces file is only used by the commands ifup and ifdown. These are called during init. However for pcmcia network cards there is no auto line so nothing happens. All control is in the pcmcia scripts. P.S. are you aware of debian-laptop? It is debian-user for laptop specific questions.
