ath driver - help needed

[Milan Obuch]

Hi,
I am evaluating ath driver with Senao AR5212 chip based miniPCI card. 
Motherboard used is Geode based WRAP. While it works well in modes 11b and 
11g, performance in 11a mode I need is suboptimal, as said in man page - even 
worse. However, test with newer driver, albeit with linux system, works much 
better.
I would like to test newer driver with FreeBSD too, but I did not succeed. I 
spent couple of hours trying to backport newer driver to 5.3, no luck yet.
Has somebody done it or could help me with this? Unfortunately I have not too 
much time to test, I need go into production some time soon.
Regards,
Milan
