It is now called ANSI X9.31 Appendix A.2.4

 http://csrc.nist.gov/CryptoToolkit/tkrng.html

and yes, there is

 NIST-Recommended Random Number Generator
 Based on ANSI X9.31 Appendix A.2.4
 Using the 3-Key Triple DES and AES Algorithms

 http://csrc.nist.gov/cryptval/rng/931rngext.pdf

Btw, anybody was lucky enough to cache the draft of X9.82 which was
posted on the NIST site some time ago?
