Or the opposite: i.e. driver requires 66 (according to some new standard**) but the device from 2009, has the 2009 standard of 32? Just a WAG, but 20110413 looks like a date, that is certainly newer than the system, though it has had firmware upgrades (though none in the past 6 months or so...)... Seems like a weird thing to be changed across drivers while not providing for some backward compat, but that's purely based on a notion that there's a driver/hw version mismatch now when before, there were no such error messages (maybe the error message is new, and it's always been broken? ;-) )... as subj says linux-3.0.0, stock vanilla + the latest IMQ networkfilter patch.
