Thinking a little bit more, I this that if we have a handle in the API 
to make some driver support multiple board, it should be given also to 
the On/Off routine and contain the relevant information so that they can 
correctly perform what you want.

Side comments : If you modify part of the API (e.g to get a vector or 
get a handle to irq handler which is what gregm has done, you should not 
complain for the resulting API not to be consistent...
