I don't know why it's not the default. I found out that it also helps for the same problem with nVidia cards. At least having an ati card means that in a couple of years there will be some good OpenSource drivers. nVidia still need to be hassled into releasing enough information for linux developers to have something to work with.
It does seem that not everyone with an nVidia or ati card is affected but it seems a bit random as to why some are and some aren't affected. Perhaps that's why it's not default. The "no Xv" allegedly means that that the work isn't being done by the onboard Gpu and is thrown back to the Cpu to deal with!!! Which does explain a few things about my Cpu and Ram usage which should never reach 50% but sometimes hovers around 40-50%. Anyway, i'm not really sure. All that i said above is just rumour and gossip but i think it's probably fairly accurate.
