rtems_interrupt_catch is only for architectures that
use Simple Vectored Interrupts.  On the x86, PowerPC,
and ARM, RTEMS uses a Programmable Interrupt Controller
interrupt model.  You need to be using the functions
defined in <rtems/irq.h>.

On the CVS head, the documentation should be a little
clearer about this.  But it may not be 100% there.  It
would be even better if the rtems_interrupt_catch()
code were disabled on architectures that didn't use it.

Sorry for the confusion.
