I guess I missed where this is the O(1) scheduler? In fact, that press release is largely content free. It just says "It's Not RTLinux."

I think you're thinking of CONFIG_PREEMPT, not the O(1) scheduler.

Perhaps this patch (ingo-O1-sched/preempt-kernel-rml-2.4.18-rc1-ingo-K3-1.patch) is what confused you? It's Robert Love's preempt patch against Ingo Molnar's O(1) scheduler.... :-)
