You need to add path to GRASS libs to LD_LIBRARY_PATH before you run
QGIS, for example

LD_LIBRARY_PATH=/osgeo/grass64/dist.x86_64-unknown-linux-gnu/lib:$LD_LIBRARY_PATH
qgis

obviously you can create an alias for QGIS + GRASS 6 and QGIS + GRASS 7 like:

alias qgis-grass6='LD_LIBRARY_PATH=/osgeo/grass64/dist.x86_64-unknown-linux-gnu/lib:$LD_LIBRARY_PATH
/your/path/to/qgis'
alias qgis-grass7='LD_LIBRARY_PATH=/osgeo/grass70/dist.x86_64-unknown-linux-gnu/lib:$LD_LIBRARY_PATH
/your/path/to/qgis'

Setting the path to GRASS 6 or 7 libs you select which version of the
provider/plugin will be loaded. Similarly there are two batch files in
OSGEO4W for QGIS + GRASS 6 and 7.

I'll send more detailed info about plugin upgrade progress after QGIS
2.9 freeze (tomorrow noon).
