Yes, radeon.runpm=0 has stopped the ACPI problem - but the latest Xorg 
xf86-video-intel driver ( 2.99.917 ) apparently does not work with the
latest xorg server (1.18.3) and gets a segmentation violation on initialization
-
S.N.A.F.U .
So, still no graphics mode under 4.5.0 until Xorg gets fixed or I can bother
building each previous Xorg server to find one that works with the intel
driver.

So, please confirm: 

In order to use the Radeon 8970M at all, currently I have no choice but to run
FGLRX closed source drivers and OpenGL user-space library stack, and
the open-source radeon drivers (both kernel and Xorg) are of no use to me?

There is no way I can use any open-source driver or OpenGL implementation
to control the card for X-Windows display use ?

Is there any xorg.conf that might potentially let me use the 
Radeon GPU for display on the laptop LCD without using FGLRX ?

I can't see how any xorg.conf can load the Radeon driver for 
the card, since that driver cannot determine the display modes .

I'll see about getting the 8970M card removed from my laptop so I can sell it
on ebay - it is of no use to me in the computer.
