In addition to disabling/enabling ACPI and kernel tweaks, it have set my ata channels from UDMA100 to PIO4 with no change (I would have expected higher load). It appears any moderately intensive disk i/o (ie extracting mozilla source) will have a unusual high impact on system load. I can provide any additional information if needed.
