It sounds like there are a number of things here where newer kernels are
breaking older userspace.  It's also causing some very end-user visible
effects, like having folks' systems auto shut down because upower thinks
their batteries are dead.

Old versions of upower are obviously confused here.  It would be really
nice to ensure that newer kernels don't break it like this.

IOW, it would be really nice if this were treated like a regression,
because it's tantalizingly close.
