this fails here:

by using wrap(hw.NIC0()) instead, io does not complain any longer.

With that change, l4linux does no longer utilize the provided callbacks 
[mach_setup.c: void register_platform_callbacks(void) -> 
l4x_register_platform_device_callback("foodevice", my_device_cb)]. So 
none of the Hw Devices is probed/found.

Am I right that the name is essential for the platform_device_callbacks 
mechanism? If so then l4linux needs that type of name.
