Debian installer detects Intel PRO/Wireless and could load firmware files from USB storage (required firmware file names provided as well). I used wired connection instead and enabled wireless later by adding firmware from non-free:
# apt-get install firmware-iwlwifi wireless-tools
After this wireless module iwl3945 is loaded automatically and wireless interface wlan0 becomes available.
PowerTOP output with fully charged battery and wireless on. Apparently nonsensical 173W. Battery is nearly new.
