Other way round, I think - with the acceleration available, the CPU can drop its frequency during playback, which isn't possible with the non-accelerated driver. I know this used to cause a problem (in that the speed change sometimes locked up when there was a lot of I/O going on) but I thought it had long since been fixed - or maybe the Fedora/CentOS kernels I've used have just had it disabled for all this time.
