[PATCH] gxfb: Fixups for the AMD Geode GX framebuffer driver
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.
