Centos 5.2 Firewall / AccessPoint using Atheros AR5212
Reaching out for some help on this one. I've come so far and learned a lot but I think I've reached the end of the road as far as my brain and google links will take me.
I've got a home firewall setup running CentOs 5.2. It's got two wired interfaces: inside and out and I'm successfully using iptables to filter and nat traffic in and out as expected.
Recently I've added an AirLink101 AWLH4030 wireless nic that is recognized as the AR5212/AR5213 chipset.
It appears that I have everything configured properly and I've eradicated every error encountered so far. Currently, I have my ath0 interface up and essid set but am unable to connect or even see the AP from my laptop.
Any help to get me over this next hurdle is massively appreciated!
Here is a metric shit ton of debug/output for any networking gurus to ponder over:

One thing I've seen referenced in my journey is "hostap_crypt", which is not present and trying to probe it gives me "FATAL: Module hostap_crypt not found." Not sure if I need it since I'm going for an OpenWiFi.
