LAPIC may lead to aliasing for softclock and profclock because frequencies are sized in order to fit mainly hardclock. atrtc used to take care of the softclock and profclock and it does still do, if the LAPIC can't handle the clocks properly. Revert the change when the LAPIC started taking charge of all three of them and let atrtc handle softclock and profclock if not explicitly requested. Such request can be made setting != 0 the new tunable machdep.lapic_allclocks or if the new device ATPIC is not present within the i386 kernel config (atrtc is linked to atpic presence).
