You will need wlan0 interface, you are not interest in wifi0.

This seems to be wlan0 interface, but why it is renamed to wlan0_rem? 
Seems that '/sbin/ifrename' or something renames the wlan0 to wlan0_ren 
at some point for some reason.

What ifup wlan0=roam will do? Why not just 'ifup wlan0' ?

Seems like the hostap_cs is still loaded, because you have wlan0 device. 
Orinoco uses ethx device naming. Are you sure your blacklistning 
actually works?
