Radeon X1000 series and earlier move to legacy support status
 

AMD has decided to switch some of its older Radeons, from the 9000 series through the X1000 series, into what is calls "legacy" support status. The move means those GPUs will no longer be included in the monthly Catalyst graphics driver drops. Instead, for the time being, they'll receive driver updates (mainly centered on bug fixes) on a quarterly basis.

They should have done that long ago... installed the latest drivers for a new XP SP3 install using a 9600XT, and the system now BSOD's upon boot.

boot into Safe VGA mode, remove driver, revert to older one

Yes, just haven't had the time to deal with it yet.
