It still needs a lot of cleanup and some bugfixes, but I'm going out on sabbatical for the next three weeks, so I thought I'd post this patch in case anyone's interested in running 2.6 on an Altix box. You'll need to apply this patch and the headless node patch I just sent out, along with a few others that have already been merged into various trees but aren't in Linus' tree yet. This patch is against Linus' bitkeeper tree as of a few hours ago. Thanks, Jesse
