Yuck. I really don't like this -- why should the board model have
to care about implementation internals of lsi53c895a? It's just
plugging in a PCI card. And why only this device and not every
storage device in every board?

Nothing should actually start happening until the whole machine model
is completely set up and we've returned control to vl.c (and probably
not until we've done our first system reset). Any device which is
doing stuff early is broken and needs fixing.
