A framebuffer driver for the display controller in AMD Geode GX processors
(Geode GX533, Geode GX500 etc.).  Tested at 640x480, 800x600, 1024x768 and
1280x1024 at 8, 16, and 24 bpp with both CRT and TFT.  No accelerated features
currently implemented and compression remains disabled.

This driver requires that the BIOS (or the SoftVG/Firmbase code in the BIOS)
has created an appropriate virtual PCI header.
