--- Comment #8 from Michael Eagle <xanto@egaming.ro> ---
Hello,

I upgraded my kernel with latest ubuntu mainline
Linux mike-g337 3.14.0-999-generic #201404040227 SMP Fri Apr 4 06:28:24 UTC
2014 x86_64 x86_64 x86_64 GNU/Linux

and also webstack from oibaf-ppa:

Upgrade: libg3dvl-mesa:amd64 (10.2~git1404021931.0f641b~gd~s,
10.2~git1404040730.4fa58a~gd~s), xserver-xorg-video-intel:amd64
(2.99.911+git1404021930.baef22~gd~s, 2.99.911+git1404031930.f05658~gd~s),
xserver-xorg-video-ati:amd64 (7.3.99+git1404021930.ed0cfb~gd~s,
7.3.99+git1404022026.ed0cfb~gd~s), xserver-xorg-video-radeon:amd64
(7.3.99+git1404021930.ed0cfb~gd~s, 7.3.99+git1404022026.ed0cfb~gd~s),
mesa-common-dev:amd64 (10.2~git1404021931.0f641b~gd~s,
10.2~git1404040730.4fa58a~gd~s)

and now, xrandr --listproviders shows the desired output:

Providers: number : 3
Provider 0: id: 0x68 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs:
4 outputs: 5 associated providers: 2 name:Intel
Provider 1: id: 0x3f cap: 0xf, Source Output, Sink Output, Source Offload, Sink
Offload crtcs: 0 outputs: 0 associated providers: 2 name:radeon
Provider 2: id: 0x3f cap: 0xf, Source Output, Sink Output, Source Offload, Sink
Offload crtcs: 0 outputs: 0 associated providers: 2 name:radeon

DRI_PRIME, also works

mike-g337 mike # DRI_PRIME=0 glxinfo  | grep 'OpenGL'
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Haswell Mobile 
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.2.0-devel
OpenGL core profile shading language version string: 3.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 10.2.0-devel
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:
mike-g337 mike # DRI_PRIME=1 glxinfo  | grep 'OpenGL'
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD HAINAN
OpenGL core profile version string: 3.1 (Core Profile) Mesa 10.2.0-devel
OpenGL core profile shading language version string: 1.40
OpenGL core profile context flags: (none)
OpenGL core profile extensions:
OpenGL version  string: 3.0 Mesa 10.2.0-devel
OpenGL shading languagew, version string: 1.30
OpenGL context flags: (none)
OpenGL extensions

Now because radeon is active, I can not remove the module from within X
anymore: 
rmmod radeon
Error: Module radeon is in use

DRI_PRIME=1 glxgears also works, I don't have any game to test now, But,
everything is fine in your opinion ?


And also, perhaps I shouldn't do this, but if I run:
 DRI_PRIME=2 glxinfo  | grep 'OpenGL'
X server crashes with the following backtrace (it wasn't crashing before):
