We cannot assume that the BIOS will be correctly setting up the hardware, so set some bits in various display registers to enable video output. Allow an advanced user to specify a frambuffer size, rather then probing the BIOS. All of these fixes were prompted by the OLPC effort.

If you want to manually specify the size of your GX framebuffer,

say Y here, otherwise say N to dynamically probe it.

Say N unless you know what you are doing.

Specify the size of the GX framebuffer. Normally, you will

want this to be MB aligned. Common values are 0x80000 (8MB)

and 0x1600000 (16MB). Don't change this unless you know what

you are doing
