[Debian-eeepc-devel] 701 battery capacity has wrong dimension?

I searched the list and googled about it, but I did not find a pointer.
On my EeePC 701 /proc/acpi/battery/BAT0/info states:
design capacity: 5200 mAh
last full capacity: 100 mAh
battery technology: rechargeable
design voltage: 8400 mV
design capacity warning: 20 mAh
design capacity low: 10 mAh
capacity granularity 1: 52 mAh
capacity granularity 2: 52 mAh
model number: 701
battery type: LION
OEM info: ASUS
Seems like last full capacity, design capacity warning, design capacity
warning are rather percentages than mAh, and design capacity, capacity
granularity 1, capacity granularity 2 are really mAh.
I do not have a second laptop to compare with other system, so I wonder
if this is normal. AFAICS the kernel module just reads the ACPI values
and reports them, expecting mAh for all capacity values, whereas the 701
gives values for %. Something's wrong.
As a result gnome-power-statistics complains about a battery that is
alway depleted and never full, which is not very helpful.
