IFD_POWER_UP should report the same ATR as IFD_RESET.

You are using a PKCS#11 library with a memory card? So all the crypto
is done in software by the PC and the private keys are read from the
memory card? Strange idea :-)

I have no idea how to use a memory card with pcsc-lite. If returning a
faked (non-null) ATR works for you then go on.
