ACPI has never been perfect, or at least it has always been sensitive to the hardware you're using. I always had trouble with ACPI and my computer (AMD Athlon 2200+ on ECS EliteGroup K7S5A mainboard). So I boot with acpi=off, and it used to be that apm could turn the power off at the end of shutdown. Since fairly recently (I moved, and wasn't keeping track, but I think it happened late in April), the computer no longer shuts itself down but instead asks me to "power off." So I tried booting without the acpi=off option, but I got the same old failure message when acpi tried to start up. I concluded that now, both apm and acpi are broken, at least with my crummy mainboard, and gave up. For what it's worth, I do blame it on my hardware--which has always seemed pretty cheap. I guess we have different problems, but something did seem to change lately in power management.
