Confirmed. I thought it was my imagination but since an update about a week ago (so, around 20th September 2007) gnome-power-manager doesn't hibernate the PC when battery level gets to critical. This had been working fine up to then and was in regular use.
I did a manual hibernate test from a fresh start, and it also fails. Screen goes blank immediately, there's no hard disk activity as you'd expect, and there is no way to interact with the PC (Ctrl+Alt+SysRq+K tried to restart GDM).
There's not much in the log files for the battery-critical event. syslog and daemon.log just show NetworkManager releasing and then re-establishing the network lease, kern.log just shows the restart, auth.log seems to show an hourly cron process at about the same time, but I think that is coincidence. Here's what could be found:
=== auth.log ===
