During early SQL Server 2008 development, the Storage Engine team introduced additional minimally-logged functionality. And then it was removed again for RTM. Now it seems that they've bowed under customer pressure and have made the functionality available again (see Sunil's announcement here).

Using trace flag 610 in the RTM build, you enable the potential for minimal-logging when:

  • Bulk loading into an empty clustered index, with no nonclustered indexes
  • Bulk loading into a non-empty heap, with no nonclustered indexes

Sunil's previous blog post here gives more info on the required syntax – very useful!
