If the module builds and loads cleanly when done manually, you 
are half way home  ;)

heh -- wpa_supplicant is 'lightly' documented, and the process 
for getting a wholly text mode wireless connection, and 
auto-selecting between open and secure with WPA or WPA2 AP's 
seems like a dark art.  The following is from memory as the 
unit in question is not physically on, and not remotely 
reachable at the moment

[As a bit of background, I was tempted by the price of an 
'e-machine' box, while travelling and a laptop died while on 
the road -- the darn thing takes non-CentOS 'wl' Broadcom 
wireless drivers, and the 'atl1c' wired network driver, of 
which I solved one manually, and the other one with a package 
from El Repo
     	/me waves to that fine effort ]

It turns out not to be a 'dark art' to get wireless networking 
on the darn thing after all, but it was not trivial, either. I 
reading man pages, tailing logs, stracing stuff, and so forth. 
Most of the effort ended up in getting the configuration 
correct in /etc/wpa_supplicant/wpa_supplicant.conf AND having 
to add a custom add on initscript, and did edits in 
/etc/sysconfig/wpa_supplicant to get the whole shebang working 
properly and hands off

Quick answer is that a script to this effect ran at step S98, 
and basically:
        	stopped networking
        	stopped a running wpa_supplicant
        	rpmmod'd an instance of my locally compiled wireless
        		driver module
        	re-loaded said custom wireless driver module
        	# [ at this point the driver REALLY loaded ]
        	[re]started the wpa_supplicant
        	[re]started the networking

and dhcp, and the wireless supplicant basically did a:
        	iwlist eth0 scan

... which then walked the enumeration of ESSID's and looked 
for a match in /etc/wpa_supplicant/wpa_supplicant.conf  Once 
found, wpa_supplicant hands along the required credential, 
and 'magic happens'

I assume there are various GUI goop tools to this effect, but 
I am not much of a GUI person ;)

I'll try to remember to write this up more formally.  Hope 
this helps
