Although I'm not convinced that this bug would warrant a release-notes entry (as 
it doesn't necessarily affect many people), let's propose a text (linux-only of 

5.1.5. Change in kernel policy regarding resource conflicts

The default setting for the acpi_enforce_resources parameter in the new Linux 
kernel version has changed to be "strict" by default. This can lead some legacy 
sensor drivers to be denied access the sensors hardware. This can be 
workarounded by setting this parameter to "lax", e.g. by appending 
"acpi_enforce_resources=lax" to the kernel boot line.

Hrm; I'm no native english speaker nor kernel specialist; I hope my text helps.
