In my case, I don't have a dhcp server but I use isc-dhcp-relay in order to reuse my master DHCP server for wireless endpoints. The advantage over one single point of control is that fixed and wireless endpoints will share the same network 192.168.0/24.
/etc/default/isc-dhcp-relay
# What servers should the DHCP relay forward requests to?
SERVERS="192.168.0.254"
# On what interfaces should the DHCP relay (dhrelay) serve DHCP requests?

Here are the results when using Larry's script:
sudo ./control_ap.sh start wlan0 eth0

I think the problem I am having is the same as without the script.
Do you want me to enable additional logging? (plz confirmed how to do so)
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.
