Why not a signature to match main():

	int MYTASK( int argc, char ** argv );

I guess the idea is to start main() routine from it ?

Are you planning to remove the call to main() from boot_card.c ?

 rtems_status_code rc;
 rc = rtems_task_start_main_style( id, main, argc, argv );

What happens when exit() &/or assert() are called ?

I guess it is important to know what we are trying to
archive here:

   + have a stardard way of starting up RTEMS.

   + making easier porting 3rd party applications

   + providing a standard configuration

All programmers expects something similar a "C" program
as an entry point for any application.
A RTEMS newbee would like to have this fisrt application,
link it against RTEMS libraries, and get up and running.
At this moment, he/she should not be worried about 
configuration, init task, stack size, prority, etc.

  int main( int argc, char**argv )
      printf( "Hello World\n" );	
      return 0;
