Well I have a NDA with the VIA, and I got the K8T890 under an NDA.

Maybe you can post a lspci -xxx -vvv for the beginning to see what SB you have. 
I will check how the NB looks like, maybe it will be quite similar.

We could also ask Bruce for the datasheet but I think he will just tell me that 
it is too old chipset ;) Best it would be to work on VX855 or VX800 because it 
is still produced.

You will also need perhaps the service manual to laptop and list of GPIO for 
various things like EC etc. Also you will need to recover the bad flash so you 
will need most likely to solder the socket for the BIOS and also you will need 
to deal with the embedded controller.
