CrunchBang Linux

I have just switched to #! and I am truly loving it.  I have a Lenovo x220 and I like tweaking my settings for good battery life. 
Currently I am using the liquorix kernel,  thinkfan,  and several boot parameters and power top reports my idle use going from 30 watts at stock down to about 15 now.  However,  powertop shows my wireless card using 10 watts almost always.  I use the power saving feature but it seems to make no difference.
Anyone have any suggestions?
