In that case, your ROM is probably not entirely mapped yet. That's an
issue that has to be fixed per chipset (southbridge mostly).
I see explicit support for it in cs5530 (even though that _might_
require some more changes), and somewhere in the code of cs5535. I don't
know if this is applicable to cs5536, too. If you want to try, this hack
might help you (untested, as I don't have the hardware). Maybe the call
must be moved around a bit.
Thanks for your effort,
