A Very Good Sign

Politcal Animal sums it up:

Back in September, Attorney General Michael Mukasey appointed Nora Dannehy, a career federal prosecutor, to pursue possible criminal charges against Republicans involved in the U.S. Attorney purge scandal.

she's hard at work and taking the controversy seriously, albeit quietly.

... "A prosecutor who is investigating the dismissals of nine U.S. attorneys has been meeting with defense lawyers, dispatching subpoenas and seeking information about the events, according to legal sources familiar with the case. [...]

"By naming a federal prosecutor to determine whether crimes have been committed, the attorney general ensured that authorities would have the power to compel testimony and documents.

The Washington Post piece noted that D. Kyle Sampson, Alberto Gonzales' chief of staff until his March 2007 resignation, "recently took a leave from his job as a partner" at a major law firm. This may or may not be related to Dannehy's investigation, but it's worth remembering that the Justice Department's Inspector General report concluded that Sampson's testimony was "not credible" and "unpersuasive."
