updated patch, vs. 2.6.9
The previous patch disabled the LAPIC too early on SMP machines.
This updated patch, suggested by Ingo Molnar, does it later.
Also, the previous patch disabled the LAPIC if it was enabled,
while this patch disables it only if Linux forced it to be enabled.
reverted 1st patch and applied 2nd patch to acpi 2.6.10 test tree.
shipped in 2.6.10-rc3.
