That's the same error message - thanks for including it.

Thanks, I just purged libatomic-ops and tried:
CFLAGS=march=native ./configure && make and drm built for me, too.
Actually, a git pull from today didn't require libatomic-ops or march=*.

There's notes about atomic_ops in the git master branch, along with a few
other suggestions:
Quote from the drm configure file:
AC_MSG_ERROR([libdrm_intel depends upon atomic operations, which were not
found for your compiler/cpu. Try compiling with -march=native, or install
the libatomics-op-dev package, or, failing both of those, disable support
for Intel GPUs by passing --disable-intel to ./configure])
Another note with drm - this time pulled from git 20091023, I also
observed this behaviour with 2.1.15, though. I just built Xorg-7.5 with
MesaLib-7.6 and MesaGLUT-7.6 and had to comment out the DRI line in
/etc/udev/rules.d/55-lfs.rules or I wouldn't get /dev/dri/card0. Can
anyone confirm this?
