Radeon KMS error: No Screens found

segfault

I am trying to use the new KMS radeon support and getting the "no screens" error:

Xorg.log: http://pastebin.com/r2S7Cr7s

I have tried with and without a xorg.conf with the same result. My xorg.conf looks like this: http://pastebin.com/c1Y8yst4

I removed all installed packages/ports using portmaster before building my KMS-ready xorg using portmaser and
Code: 
WITH_NEW_XORG="YES"
in my make.conf. Is there something obvious I am still missing? I think I've seen this error before and it was something simple but not finding much online at the moment. Any help would be appreciated!
 
You can see in the Xorg log file that the radeonkms kernel module isn't loading. Does dmesg show anything? What happens if you try to manually load the radeonkms module?

Thanks for the quick reply. kldstat show that radeonkms.so is loaded however.
dmesg shows the following:

Good idea, it mentions
Code: 
Error: Unable to locate a BIOS ROM

Any ideas?
EDIT: I see somewhat similar posts online concerning laptop/mobile video card issues but this is on my Asus desktop. this link speaks of the Linux kernel getting similar error due to EFI related reasons. I know nothing of how FreeBSD is handling the EFI booting now (if at all) so will look into this further. This is starting to look like it may be a bug.
 
Hi,
  1. The wiki page is apparently being updated, but you can read the cached older version here. As described, you need to set both of these:
    Code: 
    WITH_NEW_XORG="YES"
WITH_GALLIUM="YES"
  2. You don't need the git repos or any other trunk stuff described in the above link; the ports tree has been updated to latest commits. The "enable debug" in kernel configuration is also not necessary unless you strart to get kernel freeze/dump problems.
  3. Remove any kernel module load instruction you have in /boot/loader.conf. Xorg will lad the modules its self and you will interfere with the process if you kldload it. So none of the below.
    Code: 
    # radeon_load="YES"
# radeonkms_load="YES"
  4. Do not try and # kldload radeonkms, you will gat a black TTY screen. Using KMS means no console for now. This will be fixed with newcons, the new console implementation currently developed: https://wiki.freebsd.org/Newcons. The TTY actually works (try typing reboot and you will see that the command goes through) it just is not displayed.
  5. Re-build graphics/libGL, graphics/dri and all Xorg-related ports (like x11-drivers/xf86-video-ati and mouse, keyboard drivers). Compile for dri might break if you have enabled
    Code: 
    OPTIONS_UNSET= NLS
    so disable it.
  6. If you prefer, rerun # Xorg -configure then compare it to your existing /etc/X11/xorg.conf and make the relevant changes. Since console is disabled, you can re-start Xorg with ctrl+alt+backspace keys if you include this:
    Code: 
    Section "InputDevice"
        Identifier  "Keyboard0"
        Driver      "kbd"
        Option  "XkbOptions"    "terminate:ctrl_alt_bksp"
EndSection

Now startx. Mine works (GPU is RS880-RadeonHD-4250). Good luck.
 
These are very detailed instructions, thank you very much. I will try these tonight after work. I was familiar with the wiki page but thought I read elsewhere that the
Code: 
WITH_GALLIUM="YES"
was no longer necessary. That may be the missing link for me now.
Thank you!
