New Revision: 3785

Log:
Emulator ROM build - fix VMWare VGA adapter, from Marcin Cieslak

Send command to the PCI command port to inform the device that I/O
port has been enabled.

Issue a warning during PCI resouce allocation if "reg" property has
not been provided (with diag-switch? true).

Generate "reg" property for the PCI resource allocator.

Known to work with qemu-2.4.0.  Does not rewrite all changed
rectangles on qemu-2.0.0
