Got it! with these parameters it really works! the kernel is ubuntu
10.04 default 2.6.32-23-generic-pae,

Then these parameters mean the haredware crypto functions cannot be utilized,
all encrypt/decrypt calculations are using the main CPU, right?

Then our remaining job is still to figure out how to make it work with
enabling these
parameters; without released documents from Broadcom, we can only do
reverse engineering?
from where to start? although maybe not an easy task, but I'd like a try;

Sorry, that linux netbook with atheros is using linux 2.6.21.7, really
old kernel
I cannot update software on it because its storage is very limited, I
cannot even
install a compiler on it;
(in fact, it's EeePC 701, the very first model, with Intel Celeron 900 MB,
and only 4 GB SSD storage,)
