After a combination of kernel upgrade, BIOS downgrade (to fix an unrelated bug with resuming from suspend), KDE upgrades, and of course general "messing with stuff", now it is working most of the time. I have an actual battery meter and power management works and I am happy. I sometimes get ACPI/DSDT errors in dmesg from boot time, about infinite loops in 3 places, and when this happens the battery is either "not present" to ACPI or is present but the state never changes (for example remaining capacity at boot time is 2048 and this will remain to be the value even as battery is dying). This properly seems to happen randomly, or maybe affected somehow by dual-booting into MS Windows. I didn't think DSDT/ACPI changes by the OS were persistent? Perhaps it's something to do with warm rebooting vs powering off and back on. I will have to experiment with it some more to see if I can break it :) A long time ago I tried to extract and repair my broken DSDT but it was over my head. I don't understand why it doesn't always work but for now things seem to be functioning properly when ACPI is okay at boot time.
