 * package 2.7.0 for details)
 *
 * The SMBus PCI Device can be activated by setting a bit in the ICH LPC 
 * bridge. Unfortunately, this device has no subvendor/subdevice ID. So it 
 * becomes necessary to do this tweak in two steps -- the chosen trigger
 * is either the Host bridge (preferred) or on-board VGA controller.
 *
 * Note that we used to unhide the SMBus that way on Toshiba laptops
 * (Satellite A40 and Tecra M2) but then found that the thermal management
 * was done by SMM code, which could cause unsynchronized concurrent
 * accesses to the SMBus registers, with potentially bad effects. Thus you
 * should be very careful when adding new entries: if SMM is accessing the
 * Intel SMBus, this is a very good reason to leave it hidden.
 *
 * Likewise, many recent laptops use ACPI for thermal management. If the
 * ACPI DSDT code accesses the SMBus, then Linux should not access it
 * natively, and keeping the SMBus hidden is the right thing to do. If you
