[fireball] 27290: - Fix incompatibility: In Windows IoGetDeviceProperty(DevicePropertyAddress) returns information as 0xDDDDFFFF (D=Device, F=Function) and not as a PCI_SLOT_NUMBER structure. This is confirmed by tests in Windows XP and 2003, and also found via Google. - Fix incorrect usage of DevicePropertyAddress in videoprt and ndis (thus ndis.sys+pcnet.sys load [again] in Windows XP).

Log:
- Fix incompatibility: In Windows IoGetDeviceProperty(DevicePropertyAddress) returns
information as 0xDDDDFFFF (D=Device, F=Function) and not as a PCI_SLOT_NUMBER structure.
This is confirmed by tests in Windows XP and 2003, and also found via Google.
- Fix incorrect usage of DevicePropertyAddress in videoprt and ndis (thus
ndis.sys+pcnet.sys load [again] in Windows XP).
