In general, graphics hardware manufacturers currently do not provide built-in support for subdivision surfaces. However, there was a SIGGRAPH paper this year entitled "A realtime GPU subdivision kernel" where the authors show how to perform subdivision inside of the GPU in realtime. In their original paper, their timing results were less than impressive. However, they were using older hardware so hopefully those numbers are greatly improved on newer graphics cards. Their technique can be used for many different subdivision algorithms though they concentrate on Catmull-Clark subdivision in their paper.
