I finally finished the bug bisection that I was doing and set up an RTL8188CE 
with my script on wireless-testing 3.5.0, which is the same wireless code as you 
will get with the bleeding-edge compat-wireless. BTW, that is the wireless code 
that will be in 3.6.0 in about 3 months. When I started my script, I got the 
following:

finger@larrylap:~> sudo ./control_ap start wlan0 eth0
Starting AP mode for wlan0 at address 192.168.0.1
iptables: No chain/target/match by that name.

I was able to associate and authenticate with this new AP and connect through it 
to the Internet. Obviously this kernel does not have one of the iptables 
modules, but otherwise all is well.

What version of hostapd are you using? Mine is 1.0.

You need to use compat-wireless and make certain that hostapd is new enough. I 
think 0.7.3 would be OK.
