If this is true then if you can't see your vbios show up at 0xfffc0000 then its not in your ROM image correctly.
It's at 0xfffc0000, just copying it to 0xc0000 does not seem to work...
yep.
Ok,

section 4.
I read, read, read
well, there is spoken about a vga emulation mode, you can enable/disable this feature. The GXM Geode has therefor 4 special instructions. I think.
See the special note on page 102.
If this feature enabled, the geode registers ranges for special use in the upper memory, where? I don't know ;)
If disabled, the complete graphic instruction stuff is disabled.
I will read more and try to understand
