if you look at the script network is run first, then wireless (if the card is a
wireless one)

the hardware issues an event that the pcmcia drivers catch. 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.

This used to be fairly confusing. pcmcia had its config and the system had
another. 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.
