To get the wireless card working in this computer, the recipe 
from http://wiki.debian.org/iwlagn can be used to enable
the iwlagn kernel module.  These steps are needed 2010-02-01:

  echo 'deb http://www.backports.org/debian lenny-backports main contrib non-free' \
    >> /etc/apt/sources.list
  aptitude update
  aptitude -t lenny-backports install debian-backports-keyring
  aptitude update
  aptitude -t lenny-backports install linux-image-2.6-$(uname -r | sed 's,.*-,,g') firmware-iwlwifi wireless-tools
  reboot

This will install a updated kernel from backports.org, which
need to be security patched manually by the system administrator.
