Found in 7.0.2 beta:

1. item.Facade.state_hollow
2. item.tablet.name
3. item.redstone_chipset_chipset.name
4. tile.buildToolBlock.name
5. tile.blockRedPlasma.name
6. tile.pipeBlock.name
   Can you give them names or hide them from NEI if they are not needed? (There are an API function exist in NEI for that)

Fixed to the extent I felt is necessary.
