Does it rescan the DSDT to find new additions to ACPI devices ? I have an IBM docking station with a PCI bus inside and some other devices, and when I hot plug my IBM ThinkPad T41 in it, it does not recognize those devices. Only if I boot in dock they are usable. And the DSDT is different if I boot in dock or not. So I wander if this patch would help me to hot plug my T41 in the dock an= d all devices will be recognized. (when the patch will be for i386 too) Thx, Paul ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
