IT WORKS! Thanks to Alex, Marek, Jérôme and all the others involved!
The stack I used was (base is Debian Testing):
GPU: Hawaii PRO [Radeon R9 290] (ChipID = 0x67b1)
Linux: ~agdf5/linux:drm-next-3.17-wip (calls itself 3.16-rc4?)
libdrm: 2.4.54-1
LLVM: 3.5 RC1
libclc: Git:master/0ec7437d9c
Mesa: Git:master/74e100affc + the three patches Marek named ("radeonsi: fix
CMASK and HTILE calculations for Hawaii"; "gallium/util: add a helper for
calculating primitive count from vertex count"; "radeonsi: fix a hang with
instancing on Hawaii") and can be found on mesa-dev.
DDX: 1:7.4.0-2 + Patch from
http://people.freedesktop.org/~agd5f/0001-radeon-enable-hawaii-accel-conditionally.patch
X: 2:1.16.0-1 (1.16.0)
