| panic: isaattach: ISA bus already seen!

The i386 isa code only allows a single ISA bus:

void
isa_attach_hook(parent, self, iba)
	struct device *parent, *self;
	struct isabus_attach_args *iba;
{
        [...]
	if (isa_has_been_seen)
		panic("isaattach: ISA bus already seen!");
	isa_has_been_seen = 1;

Perhaps you could build a kernel that only allowed isa0 rather than
the current isa* (in GENERIC).
