i386 + mtrr disabled doesn't do jack.

Fresh amd64 install, installed xf86-video-ati and ran your DRM test.  Contents?  Empty.

I'm building xorg right now to make sure the displays mirror this result...I'll let you know.

I just thought about this, though.  Do you think something in my make.conf could be causing this

CPUTYPE=core2 set (that would affect kernel/world compiling).
