Setup Wireless of ThinkPad SL510 in Debian

Thinkpad sl510 has a intel wireless card:
==============

Intel(R) WiFi Link 1000 BGN

==============

Unfortunately, Debian Lenny with kernel  2.6.26 cannot support this card. You could install a 2.6.32 kernel image from backport. Follow the ref [1].
Or, you could directly compile a 2.6.33 kernel from source code. According to [3], the Intel Wireless WiFi Link 1000 is supported since 2.6.33. Follow the tutorial in [4]

Afterwards, Max installed a gui-based network manager software wicd-client.
Follow the ref [2].
