Hi Jean,

Sorry, must have hit send. Anyways.

Actually no. Not using cat. I get this error if do that:

bash-2.05b# cat 1 2 > /proc/sys/dev/sensors/via686a-isa-6000/in1
cat: 1: No such file or directory
cat: 2: No such file or directory

I can though 'echo' to it:
bash-2.05b# echo 1 2 > /proc/sys/dev/sensors/via686a-isa-6000/in1
Haven't done that before though so not sure why it changed it to:
0.99 1.99 1.07
from the defaults in there. Doesn't matter now though. Root can write
to the file using 'echo'

Does seem so, yes.

2.7.0 both, not CVS.

Not sure, Probably closer to the 2nd one. I could try not using the ebuild
below if you think it might be the problem.
