[LinuxBIOS] MB1030 / 3036 VGA comes up :D

In our BIOS for the related platform, I don't see how we're disabling PCI.  I see that we set DC_FB_ST_OFFSET (GX_BASE + 0x8310) to 0 and also DC_DUR_ST_OFFSET (GX_BASE + 0x8318).

Is the 00:12:4 a PCI address?  Does that decode to Bus 0, Device 12 (decimal?), Function 4?

Well, the graphic instructions for the geode are disabled in that case :D

because this value is writen to b8h (Graphic Control Registers)

I'm not sure what I should do next.

I think i will play around with the BC_XMAP_1 registers and will set the amd prefered values :D

Currently the whole video RAM section seems to be disabled.
