I am wondering about this thread. I am using -current on my laptop with HD3200 integrated graphics (running the ATI driver for about 2 years now with several distros, no problem at all) and 13.37 on my main rig with HD6870 (for about four weeks now). On both I have installed the proprietary drivers (just letting it install the drivers, not making the package) and simply launched
after the install. A short reboot and , hey, working like a charm. No need to blacklist anything or do other things. Just worked.
