changing from 2.6.15 to 2.6.18 breaks ipw2200 support for IBM Thinkpad x40

[Laura Creighton <lac@openend.se>]

I recently upgraded my kernel from 2.6.15 to 2.6.18.  My wireless stopped
working.  According to dmesg and modprobe, the device was there.  After
much 'barking up the wrong tree' I fixed my problem by installing 
firmware version 3.0 from Intel.   You get it here: http://ipw2200.sourceforge.net/firmware.php  after going through some Intel licensing agreement.
Once you get the file and pack it, install what you get into 
/lib/firmware.

Posted here so the next person with this problem will have a faster time
of it.
