Thanks to your comment I noticed two more things: - I probably should have used dword API variant. - There is already code in nouveau which bashes this register (nouveau_vga.c / nouveau_vga_set_decode) and it's wired to vgaarb. It seems it's set to 0 only when there is more than one card. I'm not sure how to handle it yet...
