Great! :)
Did you use layer2 patch into your kernel? Without this patch pae
module will not work!

Not hostap uses this module. hostapd uses this module.

hostapd is a user space program. In [] only other modules are listed.

I don't know if layer2 patch work on 2.6 machines. Pherhaps this is the
fault. Can you look into /proc/net/pae/* to figure out whether packets
go throug this module while authentication?

You don't need to bridge the interfaces. The client interface can have
its own address.
