I've noticed this also. Intensity was not one of the options offered with "-h" so I didn't try it. My Hawaii card reports less than half the hashrate it was getting before though. I haven't yet checked whether temperature and/or electricity consumption have gone down - perhaps it's a worthwhile trade-off. I haven't yet found a block with the new miner (12 hours in) so there's a nagging doubt that it may not be set up right, even though everything seems to be working.

Edit: Update - found a block, so that part's OK. I see there's another miner update now so I'll try that soon.
