During the boot of my g4 pb i'm getting (several times the following 
error msgs:

May  5 11:56:50 pbg4-debian kernel: [   21.382596] i2c i2c-0: PMac 
Keywest Audio: attach_adapter method is deprecated
May  5 11:56:50 pbg4-debian kernel: [   21.427364] i2c i2c-0: Please use 
another way to instantiate your i2c_client

And:

May  5 11:56:50 pbg4-debian kernel: [   22.761948] i2c i2c-0: Please use

But:

(supported)
May  5 11:56:50 pbg4-debian kernel: [   22.572851] adt746x: Thermostat

And sound is working correctly (as well as the key access by 
<fn><f3>,<fn><f4>, <fn><f5>.

Moreover i see this error:

[   12.691514] udevd[408]: failed to execute 
'/lib/udev/socket:@/org/freedesktop/hal/udev_event' 
'socket:@/org/freedesktop/hal/udev_event': No such file or directory

Thanks in advance for your patience as well as for any pointer how to 
resolve.

Cheers!
