Hi, 

I don't think so, and I prove it. Attached to this mail, you'll find a graph 
showing the differences between values in /sys/ and reported by hal and the 
script I used to generate the data. (battery discharging, AC adapter plugged 
in, then battery charging and then # /etc/init.d/hal restart).

So hal is visibly faulty and not the kernel (at least on this specific issue).

---- hal-0.5.10/hald/linux/acpi.c ----
// (...)
        /* collect batteries */
        acpi_synthesize ("/proc/acpi/battery", ACPI_TYPE_BATTERY, TRUE);
        /* collect processors */
        acpi_synthesize ("/proc/acpi/processor", ACPI_TYPE_PROCESSOR, TRUE);
        /* collect fans */
        acpi_synthesize ("/proc/acpi/fan", ACPI_TYPE_FAN, TRUE);
        /* collect AC adapters */
        acpi_synthesize ("/proc/acpi/ac_adapter", ACPI_TYPE_AC_ADAPTER, TRUE);
// (...)

Didier
