Step 1 is this - needed for X3 to compile in the current Bitkeeper tree:

--- a/arch/ppc/platforms/sandpoint_setup.c	Fri Mar 12 17:27:42 2004
+++ b/arch/ppc/platforms/sandpoint_setup.c	Fri Mar 12 17:27:42 2004

I'm just checking whether my patch works on the current
linuxppc_2_4_devel Bitkeeper. It should follow soon.

The major difference is that the i8259 cascade is on IRQ 17 on the X2,
and 16 on the X3. My suspicion is that something in the i8259 setup has
broken.
