Linux 2.4.28 breaks lm_sensors

Hi Marcelo, hi all,

We have been having reports that recent changes in the ACPI subsystem of
the Linux 2.4 kernel are breaking lm_sensors on a fairly large number of
systems. In particular, 2.4.28 is affected.

I did not report earlier because I thought the problem would be fixed by
the ACPI folks before 2.4.28 would be released. Unfortunately it wasn't.

The problem is already known, was reported for 2.6 kernels 4 months ago
and fixed there by David Shaohua. See this kernel bug report for the
detail of symptoms and the solution:

Applying the proposed patch to a 2.4.28 kernel make lm_sensors work
again on affected systems, while not causing trouble to unaffected ones
as far as I can tell.

Len, David, any reason not to apply the same fix to the 2.4 tree?
