Subject: ACPI strangeness - battery jumping to low capacity and back

Hi $ALL
My notebook is behaving somewhat oddly. The KDE battery indicator
usually shows the right amount of battery power left, although every now
and then, it jumps to a value in the range 0-10%, and then jumps back.
This is quite annoying, because it gives of all sorts of warnings about
imminent power failure.
I'm running kubuntu 7.04 with 2.6.20-15-generic from standard packages,
on a Zepto 4200 (rebranded Compal CL56)
It _seems_ -- I'm not quite sure about the causality of this -- that the
following error messages turn up in dmesg when the jump happens:
...

Maybe it has nothing to do with it? It seems to be battery-related, at
least.
Is there something else I can do to help debug the cause of these error
messages and/or the battery problem?
I've attached the output of dmidecode and acpidump, in case it's useful.
