The signal levels are reported but the noise no. I try to install the madwifi driver but it seems that cannot work in monitor mode with this card.

The feature was actually deprecated and removed from all mac80211 drivers back in March+April of last year. So it would certainly be unusual if you were using a newer kernel (2.6.35+) with noise reporting.

A search for 'noise' in the commits for the wireless-testing will bring up the relevant info for anyone that actually uses a driver that supported noise reporting.. or just use an old version of compat-wireless.
