There seems also to be need to implement some functions to do software compression and decompression, but this seems to be easy as it would be some calls to an already existing external library on the right places.

Luis,

I am currently working on the communication channels with VIA.  We are
still working on the most efficient work flow, so don't expect immediate
answers.  However if you would like to forward the chipset you are
working on I will try and obtain the relevant information for it.  I do
believe that there are some older data sheets floating around the net.
