* On some platforms, the video memory is mapped at 0 in radeon chip space

* 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.
