    Some fubar machines do it in SMM mode, and the AML code just reads memory
    regions that were updated by the SMBIOS. Or, if one is lucky, the AML
    triggers the SMI (ThinkPads do this, for example -- but I am not sure that's
    the only way a ThinkPad will cause a SMI), so it could be made to run
    protected by the lock.
