I've actually noticed those errors now on my oldest sample: the 29022 
device.  I thought on that device a long time that the tda9887 was 
hardwired and thus not controllable on the I2C bus.  (That was my 
thought years ago when I first started playing with this driver, but 
from what I know now that statement doesn't really make sense.  Probably 
worth a closer look.)

I think I'm going to have to scratch-install Debian Stable back on that 
laptop and try again - though I am still at a loss for how the distro 
could have any influence on this.  But there are no other explanations I 
can come up with, especially given that this same laptop had no trouble 
operating 29xxx devices in the past.
