I've looked at it but did not follow it further. Seems like VSA1 has
some 16bit interface, but i am not sure about vsa2. so basically one
would have to find a proper place during system bootup and just jump
into the binary, taking the structure of vsa binaries into regard.
any hints on known pitfalls? Christer?
