No.  I'm saying I haven't seen the machine crash from gkrellm polling
the battery state.  FWIW, all three crashes (before disabling that
monitor) occurred when the laptop was plugged in, and at 100% battery.

I of course can't be 100% certain the problem didn't exist before, but I
definitely have had this laptop running for a few hours in the past.
It's possible it was the ACPICA import, but the version of -CURRENT I
was running before upgrading on the 21st was only three days old or so.
