Different data point, in case this might be useful...

I did not notice before, but my values (capacity and so on) are completely
wrong. It should contain values in mWh instead of mAh.

There's a new kernel boot oprion ec_polling that you may want to try.

Now it's ok except asus_acpi module does not work any more.

It complains about generic hot key driver even when I do not have compiled
generic hot key driver in.

mWh is mAh x operational voltage. They're not "completely wrong", probably 
just whatever unit your machine's ACPI uses.

The units are not the problem, it sounds like some other ACPI bug.
