ACPI doesn't sense one of my batteries after I reinsert it

I have a Dell Latitude CPi D266XT laptop. It has two batteries in it, and ACPI senses them both, but if I remove the left one then ACPI will never detect it again even if I reinsert it.

The left battery is BAT0. The right battery is BAT1 (its slot can also be used for an internal floppy or cdrom). I should be able to remove and reinsert either or both batteries (removing both at the same time requires that I have AC power, of course), and generally this works, except that once I pull out BAT0 the system never sees it again even after I reinsert it. It still draws power from that battery; if I pull out both batteries and reinsert the left one then /proc/acpi/battery/BAT0/state says "present: no" and the Gnome battery charge monitor says I'm at 0%, but the laptop will continue to use its charge and keep running.

This has happened on several kernels I've tried, but most recently on 2.6.7-rc2.

I'd like to log this as a bug; where's the correct place for me to do so, and what additional information should I include?
