Dell Latitude D820 laptop, lspci reports the network card as:
0c:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Netwo rk Connection (rev 02)
iwlwifi driver in use, card associated via wpa_supplicant but not being
actively used

Where did that -256 for "noise" come from? It ends up confusing the
gkrellm-wifi plugin, it reports a S/N of 219dB ;)
