Sorry, I still don't have a patch for the PIT problems you're seeing,
but I did track down why the ACPI PM disappeared.

It looks like its from the patch:
i386-x86-64-fix-acpi-disabled-lapic-handling.patch


The second chunk adds:

+ if (!cpu_has_apic)
+ return -ENODEV;
+

Right before we probe for the ACPI PM timer.


Andi, is there some way we can move that to after the ACPI PM probe?

thanks
