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?
