lapic, perhaps?

Possibly your BIOS's ACPI implementation is blacklisted.

Some motherboard manufacturers consider that a motherboard that boots
Windows is "debugged" and any variation with published ACPI specs merely
means that those specifications are inaccurate. 

Problematic systems include:
        /* Compaq Presario 1700 */
        /* Sony FX120, FX140, FX150? */
        /* Compaq Presario 800, Insyde BIOS */
        /* IBM 600E - _ADR should return 7, but it returns 1 */
        "ASUS P2B-S"

http://gentoo-wiki.com/HOWTO_Fix_Common_ACPI_Problems gives other
approaches to fixing ACPI bugs.

Hope this helps,

James.
