I just had my thinkpad x60s shutdown when the second battery ran to empty, even though the first battery was completely full. I reported this as a separate bug but it was marked as a duplicate of this one, but I'm not sure what my problem has to do with hotplug of batteries -- both batteries were installed when I booted up and remained installed the whole time I was using my laptop. GPM sees both batteries, and in fact when it displayed the critical low power warning and shut down my laptop, it was also showing a 70% charge with 4 hours of runtime left.
