This set of patches requires the previous IPMI ACPI patches, at least starting with patch 4.
This set of patches fixes some fairly significant bugs with the pm_smbus device, which basically just wasn't functional beyond some very basic things. It's close to a rewrite of the state machine. After that, it adds an IPMI device on the SMBus. Then it cleans up a few small things in the IPMI ACPI handling that were SMBus specific, and adds the SMBus itself to the ACPI tables. This required adding a 2.7 machine, though I've seen a patch for that on the mailing list it has not been added to the main repository yet. -corey
