        <pre>$ sudo ./intel_reg_write 0x138064 0x8
Value before: 0xB
Value after: 0xB



btw, i tried to read this register in function i915_driver_load with the
following source code, and the result is 0x8. Not know how the register changes
from 0x8 to 0xB.
    int val = I915_READ(0x138064);
    printk("0x%x\n", val);</pre>
