The Sandpoint interrupt structure for both X2 and X3 are supported
in the linuxppc kernel.  The MPC107/EPIC are supported on other boards
as well. Due to the way Linux supports interrupts, only one Sandpoint
board interrupt mode is supported.  Read the comments in
arch/ppc/kernel/sandpoint_setup.c for instructions.

There are many features of EPIC that are not currently supported using
the current OpenPIC functions, but it does work as a standard interrupt
controller on Sandpoint.
