This reverts commit b1ee26bab14886350ba12a5c10cbc0696ac679bf, along with
the "fixes" for it that all just caused problems:

 - c4c6fa9891f3d1bcaae4f39fb751d5302965b566 "radeonfb: fix problem with
   color expansion & alignment"

 - f3179748a157c21d44d929fd3779421ebfbeaa93 "radeonfb: Disable new color
   expand acceleration unless explicitely enabled"

because even when disabled, it breaks for people. See

http://bugzilla.kernel.org/show_bug.cgi?id=12191

for the latest example.

+        * On some platforms, the video memory is mapped at 0 in radeon chip space
+        * (like PPCs) by the firmware. X will always move it up so that it's seen
+        * by the chip to be at the same address as the PCI BAR.
+        * That means that when switching back from X, there is a mismatch between
+        * the offsets programmed into the engine. This means that potentially,
+        * accel operations done before radeonfb has a chance to re-init the engine
+        * will have incorrect offsets, and potentially trash system memory !
+        *
+        * The correct fix is for fbcon to never call any accel op before the engine
+        * has properly been re-initialized (by a call to set_var), but this is a
+        * complex fix. This workaround in the meantime, called before every accel
+        * operation, makes sure the offsets are in sync.
