First, the bridge should be created.

Then wpa_supplicant should run.
After wpa_supplicant associates to the wireless access point, then dhcp should succeed.
It seems like ubuntu's network scripts don't create the bridge until too late.

Surely things are getting run in the wrong order.
First, the bridge should be created.
Then, the interfaces should be configured, joined to the bridge, and brought up.

I'm worried about the wpa_supplicant error. The file is present:
jochus@Bacardi ~ $ ls -al /sbin/wpa_supplicant
