Mabbe better to take off and develop clean room reverse-engineered one 
from the sniffs. It should not be mission impossible, but took a much 
more time. Also, it could be possible to get datasheets from the chipset 
vendor in order to develop totally new driver.

I think that is grey area. There is a lot of binary modules having GPL 
license symbol whilst code is never shared...
