There was a report this week that Mac OS X 10.6.2 will block Atom support, leaving Hackintosh owners stuck at 10.6.1. Intel's Atom processors have been used in netbooks by MSI, Dell and ASUS for their low cost and modest energy consumption. Hackintosh owners were disappointed.
Shortly after that report was published, Electronista noted that a newly-released build of 10.6.2 (10C535) brought it back. Of course, we're talking about "support" for hackintoshes in a developer build of the OS, so keep that in mind.
The moral of the story: Apple can kill this when ever they please, so have fun while you can.
