We use a switch-case statements to ensure we try to find the best suitable driver for a specific graphics card. In case we don't find such, we use the default statement to initialize the graphics card as a generic VGA adapter, if the adapter is VGA compatible. If we couldn't initialize the driver, we don't touch this adapter anymore. Also, GraphicsDevice should not be tied to a PCI::Address member, as it can be theortically be used with other buses (e.g. ISA cards).
