Oldrich's patch completely removed EXA offscreen memory defragmentation again,
which is undesirable as performance will degrade over time due to the
fragmentation. Your problem could be due to a bug in the driver or maybe an
ordering issue between the EXA Block/WakeupHandlers and those of the driver (if
any).
