thanks for testing. I followed your suggestion before pushing the patches. :)

Since 2.6.20 does not work at this point I removed it from the list of 
supported kernel versions. Unfortunately, many embedded system vendors do not 
bother to bring their drivers upstream and instead, publish "code blobs" 
limited to an old linux version. So, it makes sense for us to offer support for 
older versions as well. We could remove old versions if the effort is getting 
too high (as we just did with 2.6.20).

@Franz: I know you are stuck at 2.6.14 or something similar with your Atheros 
system but I don't think it is feasible for us to "go down" that far (unless 
you find a way). It might be easier to try pushing your Atheros beyong the 
current 2.6.21 minimum.

Marek
