I do not know what the problem with using the kernel versions of 
rtl8192{ce,cu,se,de} as an AP. I have been going through the differences between 
the version available on the Realtek web site and the kernel sources. Sorting 
out the differences is mind numbing, and will take a while to complete.

Patches will be posted on the wireless ML when I get a fix.
