Liav A 053a832fac Kernel: Simplify graphics initialization somewhat
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).
