This patch allows a custom vga driver that will give the flexibility to

code after vga is initialized for tv-out. It is one of many patches to come, including code to manipulate the graphics mmio registers, enable
the
graphics i2c data lines, and tv encoder drivers.
Should it be conditionally included via a config option? Are there other boards with the same chipset that won't want to use this TV-out initialization?
Yup there will be, I hopefully I am going to try to make the code generic enough so it can be used with other Intel 8xx and 9xx chipsets (alot of the mmio registers are the same) and put it in a common locattion. Also the tv-out drivers will open the door for other tv encoder chips, and LVDS chips for laptops (this means things like blacklight control), etc. Anyways the idea is to have a global config option for the tv chip, that way it will know which code to run and if global config option is not defined it will run just as the patch is now, the default vga init.
