There are three stages to the rollout: @p{par}

1. Before 75% are producing block.version=2 blocks: no special checking @p{brk}
2. Between 75 and 95% : block.version=2 blocks MUST have height in coinbase.  We are here. @p{brk}
3. 95% or more:  all blocks MUST be block.version=2 and MUST have height in coinbase.  Should happen soon. @p{par}

Shell script to count block versions: @p{par}


Code:
gavin$ for i in {225925..226925}; do ./bitcoind getblock $(./bitcoind getblockhash $i); done | grep version | sort | uniq -c @p{brk}
 173     "version" : 1, @p{brk}
 828     "version" : 2,
