Bug#258061: ACPI initialization hangs on Compaq Presario 2100

[Bruno Diniz <bruno.diniz@gmail.com>]

When the patch you mentioned was not applied, I could make it work
with any kernel version by simply adding a 'disable_APIC_timer' in the
beginning of acpi_bus_init, and a 'enable_APIC_timer' in the end of
this function.

By the way, what is Local APIC for? What do I lose having Local APIC disabled?

Thanks,
Bruno.
