The reason I was wondering about the IRQ is I've been trying to get 3d
stuff (like tuxracer) to run and I get the error message:

*** tuxracer error: Couldn't initialize video: X11 driver not configured
with OpenGL (Success)

Now the glxgears programs runs with about 400 fps (1024x768x24 400 mhz g3)

I can't run tuxracer compiled by me or the stock ydl3.0 one. Other 3d
stuff I compile fails as well with the same message. I'm pretty sure I
have the X and kernel configuration right. (similar settings work on an
  x86 box with a 3dfx card).

	Load    "GLcore"
         Load    "dbe"
         Load    "extmod"
         Load    "fbdevhw"
         Load    "dri"
         Load    "glx"
         Load    "record"
         Load    "freetype"
         Load    "type1"

And I'm building the kernel with 4.1 rage 128 drm support and the r128
module is loaded and there are no errors on X startup other than that
IRQ error (which is also noted in the dmesg when the r128 kernel module

also glxinfo looks ok to me so I'm having a hard time figuring out the
