Jesse Barnes provided the original version of this patch months ago, but
other changes kept conflicting with it, so it got deferred. Greg Edwards
dug it out of obscurity just over a week ago, and almost immediately
another conflicting patch appeared (Bob Picco's memory-less nodes).
I've resolved the conflicts and got it running again. CONFIG_SGI_TIOCX
is set to "y" in defconfig, which causes a Tiger to not boot (oops in
tiocx_init). But that can be resolved later ... get this in now before it
gets stale again.
