This is a separate issue, you should disable ichss:
hint.ichss.0.disabled="1"

It appears your chipset does not actually support it.  I think bruno@ 
has a patch for doing more detailed checking for systems that actually 
support it.

This is strange behavior.  Your system is never reporting the current 
battery capacity (cap = 0) even though it reports a reasonable battery 
status (charging).

Again, it does not report a valid cap off power but does report a valid 
rate of use.

Did you always have this behavior or was this introduced by my commit?
