Getting Windows Mobility Center support turn on/off wireless and bluetooth

I have installed Vista Ultimate on my Dell Inspiron 640m, and realize I can't use WMC to turn on/off my wireless/bluetooth. Originally I always use the Fn+F2 button to do my bluetooth trigger and use Intel driver for turning off my wifi in XP. Now there is no easy way to turn off wireless unless if its supported by WMC (if not its going to be Network and Sharing -> Manage Network Connections -> Select Wifi adapter->Disable -> UAC confirm... nightmare...) I really think Dell wasted unnecessary effort on the QuickSet + WMC customization, those buttons added are practically useless, instead they should make sure the turn on/off wifi thing work, as well as add something for bluetooth. Also I have been suggesting to add a cycling power mode for Fn+F2 (WiFi+BT, WiFi, BT, All Off). I am not sure this could be done though.
