To apply Mauros tda827x i2c gate control patch to 2.6.29.1 does bring back the old open/close behavior, but does not fix the broken DVB-T. This one. http://linuxtv.org/hg/v4l-dvb/rev/8424b48ea1c6 It was just the most obvious difference, but that the tda8275ac1 is not much impressed by the open gate is known and there was no disorder in open and close commands.
