Aux. Power Detect: This pin is used to notify the RTL8100B(L) of the
existence of Aux. power during initial power-on or a PCI reset.
This pin should be pulled high to the Aux. power via a resistor to detect
the Aux. power. Doing so, will enable wakeup support from ACPI D3
cold or APM power-down. If this pin is not pulled high, the
RTL8100B(L) assumes that no Aux. power exists.
