Issues bringing up wireless in %post script

[Philip Prindeville]

I have a Dell Latitude L610 that I'm trying to write a prototype
customer installer for FC5 for.  It has an Intel 2915ABG NIC.

When I try to load up the ipw2200 module from the %post script,
I see:

% modprobe -v ipw2200
insmod /lib/modules/2.6.15-1.2054_FC5/kernel/net/ieee80211/ie80211_crypt.ko
WARNING: Error inserting ieee80211_crypt (...): Operation not permitted
...

same for ieee80211.ko and ipw2200.ko ... even though they are present on
the system.

Any idea why this is happening?

I've installed the ipw2200-firmware RPM before trying to bring any of
this up...  I burned it onto the installer DVD, and added it to the 
%packages
section of the ks.cfg file.

Clues?

Thanks,

-Philip
