[CentOS] thinkpad x200 wireless LAN

On the following system:

Linux 2.6.18-128.el5 #1 SMP Wed Jan 21 10:41:14 EST 2009 x86_64 x86_64 
x86_64 GNU/Linux

the Intel 5100 pci wireless adapter appears to be detected and a 
reasonable driver is indicated (iwlagn) but the radio does not appear to 
be on, at least the little antenna like LED is off.  The radio switch is 
on and the Bluetooth LED is on.   Has any one conquered this yet?
