it's a start, but there are some serious implications.

but first: what is your signal (dBm) reading (iwconfig / iw dev wlanX info)?

I'm asking this because your device is only fine-tunable for
channel 1, 7, 13 & 14 with the current data points.

some performance figures would be nice as well.
e.g.: iperf (tcp) should be > 18Mbit/s,
      if you are close & free line of sight

second: what should we do about these devices?

Surely, the best thing would be to simply reprogram the eeprom,
but this (being complicated work) requires soldering skills/tools,
a steady hand and enough boredom. Therefor this is likely the least
ideal option to put into the WIKI @ wireless.kernel.org .
Any suitable ideas?
