No. About 99% of the drivers don't have any xrender acceleration. I think only the mga driver does. Although looking furthur the sis has some, but it seems disabled, and the vmware driver has it too. But that's it. I guess nvidia do some acceleration in their binary drivers though, as you've probably found. But it's bad to assume other drivers have xrender acceleration. I think the thing that's holding other drivers up in getting furthur xrender acceleration is that there's no test suite to check that the driver is doing the right thing. I think Keith Packard mentioned he had intern's working on a test suite a while ago, but nothing has materialized as far as I know.
