Tidy NOTES a bit: - ath(4) is the last listed device, so make it's comment last as well - since we have hints for le(4), bring it back by inserting commented   out line until I check, if it can be safely enabled. - bring snc(4) explanation - put pmtimer comment together with other drivers' comments in a block - bring comments for canbus, canbepm, pmc
