Any word on new Vista RC2 drivers?

I have an X1900XT and the native drivers kept crashing, I downloaded
Catalyst Beta Driver for Windows Vista RC1 and it also kept giving me some
message about R300 critical error recovery - not a BSOD but a little popup
in the bottom right hand corner of the screen. It would go black and then
I'd get the popup. Couldn't run screen savers or whatever the middle thing
is in the right hand side of the screen below the clock. I rebooted after
install - same issue. I checked the device drivers and it said they were
the ATI drivers. I'm sure it worked for some people but it isn't working on
my system so no need to let me know that it worked on your system. I
installed twice on a clean hard drive.
