Supporting an externally triggered callback would allow someone to use RTAI 
if they need hard rt latency.  Your current driver won't work with 
comedi's RT support due to your use of tasklets.  If you want to simulate 
commands, do something like comedi_rt_timer (or enhance comedi_rt_timer) 
which would provide a simulated command for any driver that supports an 
externally triggered callback.
