Because when you make statements like...
Except to enable the BAR and read it from the assigned address...
That statement doesn't hold true for laptops. It indicates that you may not be aware of all of the issues around VGA bus routing and video ROMs. For example there are a lot of special issues with VGA support in large large machines like the SGI Altix that have multiple independent PCI domains. Owners of all of these other architectures (PPC especially) having been beating me up for two years making me aware of all of their weird cases.
