It looks like this has been resolved by upstream. We will monitor the patch for inclusion into Linus mainline dev kernel. The patch was just submitted to the linux-acpi mailing list on 8/11. [1] From the mailing lists responses, it looks like they are targeting 2.6.28 for these patches as the upstream developers have reservations. The only workaround I was able to see was acpi=off, which isn't such a great option for everyone.

Now waiting for their action. I got the same problem: kacpi_notify and kacpid uses ~90% of the CPU and unable to kill them (kernel processes) just after I disconnected the AC plug. I applied the patch [1] (change ACPI scan order) on my kernel 2.6.26 (Debian Sid 2.6.26-4) and the problem is fixed! I'm using Debian Sid on a Dell Latitude D520.
