win7 64 bit 5850+4850 100%cpu just like before.
Yes, sadly, no solution for windows, seems to be fixed for linux though.
Catalyst 11.6 works for me on Weendoze XP 32 bit. I get better hash rates and lower temperatures with no 100% pinned CPU core, nor one core's worth of load spread out 50% per core over 2 cores. I saw the latter behavior with some post-11.6 driver version, I don't recall which one.
