You can not use IRQ2 for anything under Unix - it is already used by the
system.  The asy driver should be able to use IRQ5 (I may be wrong here)
by the use of ttypattch.  The asy driver is hardwired to use a certain set 
of IRQ lines and I don't have the sources anymore to look it up.  Look
at thhe output of nm on the asy.o driver found in /usr/linkkit/lib*.a
you will find routines of the name asyXintr where x is the IRQ number
of the supported lines.
