Maybe the pcmcia services need to be configured for that to work. On
my laptop I must manually run 'ifup eth0' to bring up the interface
after (re)inserting the NIC.
However, the interfaces file isn't a problem. I use a solution
provided by someone else on this list a long time ago :
auto eth0
iface eth0 inet dhcp
pre-up /usr/local/sbin/check-link.sh
The pre-up line runs the command first, and only attempts to bring up
the interface if it exits successfully. That script is attached. It
depends on the 'net-tools' package. The only problem here is that
ifup still records the link in /etc/network/ifstate even when it isn't
brought up. Using 'ifup --force' or 'ifdown ; ifup' when the card is
inserted later works around that (as does editing the ifstate file).
