-->Charging is working fine on my device.

-->SGX
Most probably I have missed something important, but SGX does not work.. I've installed the sgx-bin and fbdev-sgx packages started the powervr service, some sgx processes are there,but just have fbdev seg fault in Xorg.log

Do you have any idea?

-->USB NIC
I've one, based on AX88178 chip, already compiled its driver on N900. I'll test it just need proper cable to be able to connect (USB NIC<-->N900).

-->Overclocking
Is that already possible in any similiar way as with kernel-power?
