Hello,

the debug infos show following when I try to modprobe speedstep-centrino.

    speedstep-centrino: Invalid control/status registers (1 - 1)
    speedstep-centrino: <6>speedstep-centrino: invalid ACPI data
    speedstep-centrino: <6>speedstep-centrino: found unsupported CPU
    with Enhanced SpeedStep: send /proc/cpuinfo to Jeremy Fitzhardinge
    <jeremy@goop.org>
    speedstep-centrino: Invalid control/status registers (1 - 1)
    speedstep-centrino: <6>speedstep-centrino: invalid ACPI data

cpuinfo follows
