A call to agp_gen5_get_gtt_total_entries returns ENXIO, what i found is that in my case (gcc1 & AGP_G4x_GCC1_SIZE_MASK) == 0xb00. I did a cross check with Linux and there isn't such a valid value defined but the Linux code does not error on default case, it continues with our agp_i965_get_gtt_total_entries() equivalent. After this change, X starts but the image has artifacts. It's progress :) Thank you for your work! xorg log: http://pastebin.com/a0zak5LY
