I've found a workaround replacing in the init script:

if ifup -a $exclusions $verbose && ifup_hotplug $exclusions $verbose
then
log_action_end_msg $?
else
log_action_end_msg $?
fi

with this:

if [ $(runlevel) != "unknown" ] || ! [ -z $(grep '^id:1:initdefault:$' /etc/inittab) ]; then
  if ifup -a $exclusions $verbose && ifup_hotplug $exclusions $verbose
  then
    log_action_end_msg $?
  else
    log_action_end_msg $?
fi
fi

which means: "skip these lines if the boot process still has not switched to the default runlevel,
unless it is single user". The following script located in /etc/boot.d:

#!/bin/sh -e
#
# networking-restart
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.

if test -x /etc/init.d/networking ; then
    service networking restart
fi

will restart the service and from this moment, both "auto <device>" and "allow-hotplug <device>" will take effect.
This way, the delay will occur only in the case of a single user default runlevel, which is often not the case.

Cheers,

Aitor.
