    As far as I could see, none of the posted patches are needed, or rather
    the correct one(s) is already included in the kernel. The older ones
    were workarounds, not needed anymore, thus obsolete.

    The only problem is the apic timer thing. It just gets activated if the
    correct BIOS Version is found (see the dmi scan thingie). So I just pass
    acpi_skip_timer_override to the kernel to be sure.

    It is safe but makes your CPU hotter. Thus the real fix just changes the
    disconnect intervall (or alike). Look into arch/i386/pci/fixup.h and
    search for nforce2.
