speedstep won't load even with acpi tables (lil more)

Hay, sorry I'm very new to Linux. I don't know much about kernel module debugging. However I was able to find the load is crapping out in the call to cpufreq_register_driver by adding some printk's :). In that function... its returning -EBUSY at ...

    if (cpufreq_driver) {
        spin_unlock_irqrestore(&cpufreq_driver_lock, flags);
        return -EBUSY;
    }

An uneducated guess tells me something is already accessing the neccessary resource?
