Yesterday I've published a patch that implements an ACPI battery driver fro Haiku OS.

The patch could be directly downloaded by using this link.

Simple apply the patch against trunk and remember to enable ACPI that's disabled by default. Then recompile your haiku image.

Following a screenshot of VirtualBox running Haiku with acpi battery driver enabled :)

Take a look to this video that presents the new fingerprint module introduced in PacketManipulator:

It has the same behavior of ettercap.
