I gave you the cite for the article. I don't have access to Science online so I can't post it, not like it would have any weight as to what it actually says (according to aharvey, anyway). I got the info of the findings from other news outlets.
What guesswork or you talking about and how would a creationist have a superior "guess" on noncoding DNA sequences?
Basically they said the same thing they did when they were "suprised" by how different chimps and humans are. Only differnce is, they thought humans and these different kinds of animals would be different and were "suprised" how exactly the same they were.

Hundreds of stretches of DNA may be so critical to life's machinery that they have been “ultra-conserved” throughout hundreds of millions of years of evolution. Researchers have found precisely the same sequences in the genomes of humans, rats, and mice; sequences that are 95 to 99 percent identical to these can be found in the chicken and dog genomes, as well.
Most of these ultra-conserved regions do not appear to code for proteins, but may instead play a regulatory role. Evolutionary theory suggests these sequences may be so central to mammalian biology that even small changes in them would compromise the animal's fitness.
Led by Howard Hughes Medical Institute investigator David Haussler, at the University of California at Santa Cruz, the researchers published their findings online May 6, 2004, in Science Express, the Web counterpart of the journal Science. The lead author on the paper was Gill Bejerano in Haussler's laboratory. Also co-authoring the paper were John Mattick and his colleagues from the University of Queensland in Australia.
According to Haussler, the researchers were launched on their analysis when initial studies hinted at major regions of conserved DNA sequences. “When we had compared the human and mouse genomes, we found that about five percent of each of these showed some kind of evolutionary selection that partially preserved the sequence,” he said. “We got excited about this because only about 1.5 percent of the human genome codes for protein. So five percent was about three times as much as one might expect from the standard model of the genome, in which it basically codes for proteins, with a little bit of regulatory information on the side, and the rest is nonfunctional or “junk” DNA.

These amazing discoveries shrowded in evo. How sad. How many times does that phrase have to be repeated and then debunked before they quit saying it? "and the rest is nonfunctional or “junk” DNA." Look what they have turned up so far in areas of DNA research alone that has proven there is less "junk" and way more, "I don't understand that part yet."
Anyway...
These initial findings suggested that quite a lot of the genome was performing some kind of regulatory or structural role - doing something important other than coding for proteins,” said Haussler.
When the rat genome sequence became available, the researchers decided to search for the most extreme cases of conservation among the three mammalian species. They looked for long stretches of DNA, at least 200 base-pairs in a row, that were identical among humans, rats and mice. Statistically, the likelihood that a sequence of this length would appear unchanged among all three genomes by chance was infinitesimally small.
In many different kinds we see exact similarities. The DNA is coded in itself to not change these parts. Why? because if these parts change the organism dies ( tiny changes over time "would compromise the creature's fitness" ). Now that is a miracle. Magic if you want to atribute it to mother nature.
