Nice try, but I think this qualifies as interface abuse of the year. :)
The problem is that I can't dynamically allocate the 'type' argument
to bus_alloc_resource.
Doug, what do you think? Is there a way to dynamically make new
types? Or an easy way to make indepenant busses so that I can
allocate different sequences not pre-compiled into newbus?
thanks,
