Wireless LED: solved by module parameter

At some point, my wireless LED stopped working again, after I thought I had solved it by enabling the extra kernel options mentioned in a previous post.  It was no big deal, so I ignored it.  Then, whilst searching for something else wireless related, I happened upon this laptop matrix about RF switches!  There I learnt that passing led=1 as a parameter to the ipw2200 module will enable the LED.  Hallelujah.  Why the LED worked in the past before I ever knew about this remains a mystery.
