ATI 9.11 beta drivers.
Source 3/4 of the page down
Edit: I just downloaded these and the installer is for Windows 7. I have X64 but it should work on X86 and maybe Vista but you will have to try it out to be sure. Also (for those that do not know) Win 7 support means these are not for XP, but I will update the OP when they come out.
Edit added XP 9.11 beta drivers
