I wondered about that - currently the 2nd channel of the opb_timer is 
unused, it could be configured as a one-shot timeout - the trick is of 
course that there would only be one available in the system - the device 
driver would have to hook into the existing timer interrupt handler, and 
so on.  An interesting experiment though.

Does anyone know if there's a precedent in other linux's for this sort 
of thing?
