after been stack on 2.6.19.7 kernel for some time due to stability and performance reasons, I was able to successfully boot a 2.6.30.1 kernel today that performs well, at least on lan connectivity as I haven't tested wifi yet. BTW, I only use atheros wifi cards as broadcom is still missing the train on the wifi open source arena.
