When working with ipw device one needs to install package 
sysutils/ipw-firmware.  This package installs the required firmware in 
/usr/pkg/libdata/if_ipw.  When the system boots it attempts to find the 
firmware from FIRMWAREPATHS 
pkg/libdata" (../dev/firmware.c line 80).

If /usr is on a different partition than root the firmware is not loaded if it 
is not in /libdata/firmware/if_ipw.  I believe this is because /usr is not 
mounted at this point.

A workaround is to copy the /usr/pkg/libdata/if_ipw directory to 

There may be some way to require /usr to be mounted before the ipw driver 
attempts to read the firmware. 

The message which shows up is:
ipw0: could not cache the firmware (ipw2100-1.2.fw)

Have /usr on a differnt partition than root, remove firmware from 
/libdata/firmware/if_ipw have a ipw device.
After installing package sysutils/ipw-firmware copy /usr/pkg/libdata/if_ipw to 


don't mount /usr on a different partition.
