Thanks for your good comments. I'll post a revised kernel patch soon.

ADT7461 will only be supported in lm90-compat mode.

Patch to add adt7461 support to lmsensors-2.9.0 is attached. I'm new to
the internals of lmsensors so I may not have done all I need to.

I'm unable to test it since I can't run sensors on my target
which is an embedded ppc board and lmsensors won't cross-compile. I
don't have enough space to run perl anyway! :)
