Hi, Errors like that would go down to the reason that your module was not built using the kernel currently running on you dev phone. Though I was only able to do such things with 2.6.27 and 2.6.29 kernel, I still think it would apply to 2.6.25. Did you replace the kernel in your phone with your downloaded kernel?
