You haven't mapped descriptors window. Seems to me it should look like this:
static void or1200_net_init(MemoryRegion *address_space,
target_phys_addr_t base,
target_phys_addr_t descriptors,
qemu_irq irq, NICInfo *nd)
{
DeviceState *dev;
SysBusDevice *s;
dev = qdev_create(NULL, "open_eth");
qdev_set_nic_properties(dev, nd);
qdev_init_nofail(dev);
s = sysbus_from_qdev(dev);
sysbus_connect_irq(s, 0, irq);
memory_region_add_subregion(address_space, base,
sysbus_mmio_get_region(s, 0));
memory_region_add_subregion(address_space, descriptors,
sysbus_mmio_get_region(s, 1));
}

Also I haven't found where 0x92100000 comes from.
Is there a memory map documentation for this machine?
