Update: As noted by our commenters and cross-confirmed with OS News, the 10.6.2 update appears to drop support for the hackintosh-centric Atom processor. This was spotted in earlier builds, but it was not clear whether the support for the netbook CPU would be in or out in the final configuration.
We've been expecting Mac OS X 10.6.2 for a while now, especially since Apple initially said that the new Magic Mouse would require it, but it has just arrived.
