I can verify that I used the *desktop-image* build from 0827 and the wifi performance was much better.   Indeed, I can now sustain an RDP (5) session at 1200x740 with "lan" features turned on using the wifi.   It is not perfect, but it is usable.   
I can also verify that this version took quite a while (maybe 30 minutes) to do all the initial processing for the first run.   It loads in the normal time subsequently.   
I should point out that there are some problems with this build.   First, it is missing libstdc++6   (easy to add with opkg).   Also, I can not get sound to work.   mplayer says that /dev/dsp is busy, however I have no idea why that would be.   It works fine with the original code shipped with the COM.

for me with the latest firmware there are still the errors dropped
packets and watchdog issues with it. It performs worse than any other
adapter I have tried with the overo. I think there is still issues
that need work and sorting out with the on board adapter, hopefully
its gets figured out and sorted properly soon because to me I still
see the on board wifi as useless as its reliability is crap.
