- The stuff in arch/ppc/boot/mvme2100 can go.
- The open_pic.c change shouldn't be needed either.
- Your openpic_initsenses table looks wrong, and is probably the cause
  of the uart slowness you found.  What you do is only list the IRQs for
  which you have something, and use openpic_set_sources calls to skip
  over the gaps.  Look at lopec_init_IRQ and ask if you still have
  problems.  I hoped to have documented that one well the first time
  around. :)
- In mvme2100_set_bat, try something along the lines of:
{
	mb();
	mtspr(DBAT1U, 0xf8000ffe);
	mtspr(DBAT1L, 0xf800002a);
	mb();
}
